Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85240, here are decompositions:

  • 3 + 85237 = 85240
  • 11 + 85229 = 85240
  • 17 + 85223 = 85240
  • 41 + 85199 = 85240
  • 47 + 85193 = 85240
  • 107 + 85133 = 85240
  • 131 + 85109 = 85240
  • 137 + 85103 = 85240

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85240 first appears in π at position 109,973 of the decimal expansion (the 109,973ordinal-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.
