%N Position of start of first occurrence of prime(n) after the decimal point in expansion of golden ratio phi.
%e Golden ratio phi = 1.6180339887498948482045868343656381177... (see A001622).
%e First occurrence of prime(1) = 2 is at the 19th digit after the decimal point, hence a(1) = 19.
%e First occurrence of prime(5) = 11 starts at the 34th digit after the decimal point, hence a(5) = 34.
