Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28926, here are decompositions:

  • 5 + 28921 = 28926
  • 17 + 28909 = 28926
  • 47 + 28879 = 28926
  • 59 + 28867 = 28926
  • 67 + 28859 = 28926
  • 83 + 28843 = 28926
  • 89 + 28837 = 28926
  • 109 + 28817 = 28926

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28926 first appears in π at position 85,966 of the decimal expansion (the 85,966ordinal-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.
