Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38186, here are decompositions:

  • 3 + 38183 = 38186
  • 19 + 38167 = 38186
  • 37 + 38149 = 38186
  • 67 + 38119 = 38186
  • 73 + 38113 = 38186
  • 103 + 38083 = 38186
  • 139 + 38047 = 38186
  • 193 + 37993 = 38186

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38186 first appears in π at position 84,368 of the decimal expansion (the 84,368ordinal-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.
