Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8870, here are decompositions:

  • 3 + 8867 = 8870
  • 7 + 8863 = 8870
  • 31 + 8839 = 8870
  • 67 + 8803 = 8870
  • 109 + 8761 = 8870
  • 139 + 8731 = 8870
  • 151 + 8719 = 8870
  • 157 + 8713 = 8870

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8870 first appears in π at position 16,772 of the decimal expansion (the 16,772ordinal-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.
