Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87250, here are decompositions:

  • 29 + 87221 = 87250
  • 71 + 87179 = 87250
  • 101 + 87149 = 87250
  • 131 + 87119 = 87250
  • 167 + 87083 = 87250
  • 179 + 87071 = 87250
  • 239 + 87011 = 87250
  • 257 + 86993 = 87250

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 87250 first appears in π at position 97,713 of the decimal expansion (the 97,713ordinal-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.
