Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31292, here are decompositions:

  • 43 + 31249 = 31292
  • 61 + 31231 = 31292
  • 73 + 31219 = 31292
  • 103 + 31189 = 31292
  • 109 + 31183 = 31292
  • 139 + 31153 = 31292
  • 211 + 31081 = 31292
  • 223 + 31069 = 31292

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31292 first appears in π at position 480,169 of the decimal expansion (the 480,169ordinal-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.
