Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29140, here are decompositions:

  • 3 + 29137 = 29140
  • 11 + 29129 = 29140
  • 17 + 29123 = 29140
  • 107 + 29033 = 29140
  • 113 + 29027 = 29140
  • 131 + 29009 = 29140
  • 179 + 28961 = 29140
  • 191 + 28949 = 29140

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29140 first appears in π at position 250,763 of the decimal expansion (the 250,763ordinal-suffix:rd 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.
