Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37870, here are decompositions:

  • 17 + 37853 = 37870
  • 23 + 37847 = 37870
  • 59 + 37811 = 37870
  • 71 + 37799 = 37870
  • 89 + 37781 = 37870
  • 179 + 37691 = 37870
  • 227 + 37643 = 37870
  • 251 + 37619 = 37870

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 37870 first appears in π at position 71,845 of the decimal expansion (the 71,845ordinal-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.
