Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89920, here are decompositions:

  • 3 + 89917 = 89920
  • 11 + 89909 = 89920
  • 23 + 89897 = 89920
  • 29 + 89891 = 89920
  • 53 + 89867 = 89920
  • 71 + 89849 = 89920
  • 101 + 89819 = 89920
  • 137 + 89783 = 89920

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 89920 first appears in π at position 115,459 of the decimal expansion (the 115,459ordinal-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.
