Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39812, here are decompositions:

  • 13 + 39799 = 39812
  • 43 + 39769 = 39812
  • 79 + 39733 = 39812
  • 103 + 39709 = 39812
  • 109 + 39703 = 39812
  • 181 + 39631 = 39812
  • 193 + 39619 = 39812
  • 271 + 39541 = 39812

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39812 first appears in π at position 178,093 of the decimal expansion (the 178,093ordinal-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.
