Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37890, here are decompositions:

  • 11 + 37879 = 37890
  • 19 + 37871 = 37890
  • 29 + 37861 = 37890
  • 37 + 37853 = 37890
  • 43 + 37847 = 37890
  • 59 + 37831 = 37890
  • 79 + 37811 = 37890
  • 107 + 37783 = 37890

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 37890 first appears in π at position 16,422 of the decimal expansion (the 16,422ordinal-suffix:nd 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.
