Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83408, here are decompositions:

  • 7 + 83401 = 83408
  • 19 + 83389 = 83408
  • 67 + 83341 = 83408
  • 97 + 83311 = 83408
  • 109 + 83299 = 83408
  • 139 + 83269 = 83408
  • 151 + 83257 = 83408
  • 181 + 83227 = 83408

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 83408 first appears in π at position 8,500 of the decimal expansion (the 8,500ordinal-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.
