Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28974, here are decompositions:

  • 13 + 28961 = 28974
  • 41 + 28933 = 28974
  • 47 + 28927 = 28974
  • 53 + 28921 = 28974
  • 73 + 28901 = 28974
  • 103 + 28871 = 28974
  • 107 + 28867 = 28974
  • 131 + 28843 = 28974

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28974 first appears in π at position 516,917 of the decimal expansion (the 516,917ordinal-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.
