Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65140, here are decompositions:

  • 11 + 65129 = 65140
  • 17 + 65123 = 65140
  • 29 + 65111 = 65140
  • 41 + 65099 = 65140
  • 107 + 65033 = 65140
  • 113 + 65027 = 65140
  • 137 + 65003 = 65140
  • 239 + 64901 = 65140

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65140 first appears in π at position 298,497 of the decimal expansion (the 298,497ordinal-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.
