Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86320, here are decompositions:

  • 23 + 86297 = 86320
  • 29 + 86291 = 86320
  • 71 + 86249 = 86320
  • 137 + 86183 = 86320
  • 149 + 86171 = 86320
  • 251 + 86069 = 86320
  • 293 + 86027 = 86320
  • 389 + 85931 = 86320

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86320 first appears in π at position 128,705 of the decimal expansion (the 128,705ordinal-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.
