Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64090, here are decompositions:

  • 23 + 64067 = 64090
  • 53 + 64037 = 64090
  • 71 + 64019 = 64090
  • 83 + 64007 = 64090
  • 113 + 63977 = 64090
  • 227 + 63863 = 64090
  • 233 + 63857 = 64090
  • 251 + 63839 = 64090

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64090 first appears in π at position 6,332 of the decimal expansion (the 6,332ordinal-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.
