Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28964, here are decompositions:

  • 3 + 28961 = 28964
  • 31 + 28933 = 28964
  • 37 + 28927 = 28964
  • 43 + 28921 = 28964
  • 97 + 28867 = 28964
  • 127 + 28837 = 28964
  • 151 + 28813 = 28964
  • 157 + 28807 = 28964

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28964 first appears in π at position 8,902 of the decimal expansion (the 8,902ordinal-suffix:nd 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.
