Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8104, here are decompositions:

  • 3 + 8101 = 8104
  • 11 + 8093 = 8104
  • 17 + 8087 = 8104
  • 23 + 8081 = 8104
  • 167 + 7937 = 8104
  • 197 + 7907 = 8104
  • 227 + 7877 = 8104
  • 251 + 7853 = 8104

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8104 first appears in π at position 17,248 of the decimal expansion (the 17,248ordinal-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.
