5 is in the sequence because 5 is both Fibonacci(5) and 2+3. 2584 is Fibonacci(18) and 2+3+5+7+11+...+151+157 (first 37 primes)

PROG

(PARI) { ps=2; pc=1; fc=1; while (fc<50, while (ps<=fibonacci(fc), if (ps==fibonacci(fc), print1(ps"; "fc", ")); ps+=prime(pc++)); fc++) }

CROSSREFS

Sequence in context: A101341 A079014 A215436 * A187604 A082815 A115893
