Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99900, here are decompositions:

  • 19 + 99881 = 99900
  • 23 + 99877 = 99900
  • 29 + 99871 = 99900
  • 41 + 99859 = 99900
  • 61 + 99839 = 99900
  • 67 + 99833 = 99900
  • 71 + 99829 = 99900
  • 83 + 99817 = 99900

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 99900 first appears in π at position 31,901 of the decimal expansion (the 31,901ordinal-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.
