Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87616, here are decompositions:

  • 3 + 87613 = 87616
  • 29 + 87587 = 87616
  • 59 + 87557 = 87616
  • 107 + 87509 = 87616
  • 173 + 87443 = 87616
  • 233 + 87383 = 87616
  • 257 + 87359 = 87616
  • 293 + 87323 = 87616

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 87616 first appears in π at position 54,377 of the decimal expansion (the 54,377ordinal-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.
