Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28976, here are decompositions:

  • 43 + 28933 = 28976
  • 67 + 28909 = 28976
  • 97 + 28879 = 28976
  • 109 + 28867 = 28976
  • 139 + 28837 = 28976
  • 163 + 28813 = 28976
  • 223 + 28753 = 28976
  • 307 + 28669 = 28976

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28976 first appears in π at position 164,229 of the decimal expansion (the 164,229ordinal-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.
