Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99806, here are decompositions:

  • 13 + 99793 = 99806
  • 19 + 99787 = 99806
  • 73 + 99733 = 99806
  • 97 + 99709 = 99806
  • 127 + 99679 = 99806
  • 139 + 99667 = 99806
  • 163 + 99643 = 99806
  • 199 + 99607 = 99806

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 99806 first appears in π at position 8,012 of the decimal expansion (the 8,012ordinal-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.
