Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8906, here are decompositions:

  • 13 + 8893 = 8906
  • 19 + 8887 = 8906
  • 43 + 8863 = 8906
  • 67 + 8839 = 8906
  • 103 + 8803 = 8906
  • 127 + 8779 = 8906
  • 193 + 8713 = 8906
  • 199 + 8707 = 8906

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8906 first appears in π at position 6,338 of the decimal expansion (the 6,338ordinal-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.
