Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47158, here are decompositions:

  • 11 + 47147 = 47158
  • 29 + 47129 = 47158
  • 47 + 47111 = 47158
  • 71 + 47087 = 47158
  • 101 + 47057 = 47158
  • 107 + 47051 = 47158
  • 239 + 46919 = 47158
  • 257 + 46901 = 47158

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47158 first appears in π at position 84,349 of the decimal expansion (the 84,349ordinal-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.
