Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99920, here are decompositions:

  • 13 + 99907 = 99920
  • 19 + 99901 = 99920
  • 43 + 99877 = 99920
  • 61 + 99859 = 99920
  • 97 + 99823 = 99920
  • 103 + 99817 = 99920
  • 127 + 99793 = 99920
  • 199 + 99721 = 99920

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 99920 first appears in π at position 11,197 of the decimal expansion (the 11,197ordinal-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.
