Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37872, here are decompositions:

  • 11 + 37861 = 37872
  • 19 + 37853 = 37872
  • 41 + 37831 = 37872
  • 59 + 37813 = 37872
  • 61 + 37811 = 37872
  • 73 + 37799 = 37872
  • 89 + 37783 = 37872
  • 173 + 37699 = 37872

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 37872 first appears in π at position 353,281 of the decimal expansion (the 353,281ordinal-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.
