Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85040, here are decompositions:

  • 3 + 85037 = 85040
  • 13 + 85027 = 85040
  • 19 + 85021 = 85040
  • 31 + 85009 = 85040
  • 61 + 84979 = 85040
  • 73 + 84967 = 85040
  • 79 + 84961 = 85040
  • 127 + 84913 = 85040

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85040 first appears in π at position 237,761 of the decimal expansion (the 237,761ordinal-suffix:st 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.
