Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87086, here are decompositions:

  • 3 + 87083 = 87086
  • 37 + 87049 = 87086
  • 73 + 87013 = 87086
  • 127 + 86959 = 87086
  • 157 + 86929 = 87086
  • 163 + 86923 = 87086
  • 229 + 86857 = 87086
  • 367 + 86719 = 87086

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 87086 first appears in π at position 75,244 of the decimal expansion (the 75,244ordinal-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.
