Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90866, here are decompositions:

  • 3 + 90863 = 90866
  • 19 + 90847 = 90866
  • 43 + 90823 = 90866
  • 73 + 90793 = 90866
  • 79 + 90787 = 90866
  • 157 + 90709 = 90866
  • 163 + 90703 = 90866
  • 283 + 90583 = 90866

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 90866 first appears in π at position 9,554 of the decimal expansion (the 9,554ordinal-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.
