Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71618, here are decompositions:

  • 67 + 71551 = 71618
  • 139 + 71479 = 71618
  • 181 + 71437 = 71618
  • 199 + 71419 = 71618
  • 229 + 71389 = 71618
  • 271 + 71347 = 71618
  • 277 + 71341 = 71618
  • 331 + 71287 = 71618

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71618 first appears in π at position 144,978 of the decimal expansion (the 144,978ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
