Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88990, here are decompositions:

  • 53 + 88937 = 88990
  • 71 + 88919 = 88990
  • 107 + 88883 = 88990
  • 137 + 88853 = 88990
  • 173 + 88817 = 88990
  • 179 + 88811 = 88990
  • 191 + 88799 = 88990
  • 197 + 88793 = 88990

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 88990 first appears in π at position 22,789 of the decimal expansion (the 22,789ordinal-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.
