Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42928, here are decompositions:

  • 5 + 42923 = 42928
  • 29 + 42899 = 42928
  • 89 + 42839 = 42928
  • 107 + 42821 = 42928
  • 131 + 42797 = 42928
  • 191 + 42737 = 42928
  • 227 + 42701 = 42928
  • 239 + 42689 = 42928

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42928 first appears in π at position 104,044 of the decimal expansion (the 104,044ordinal-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.
