Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8408, here are decompositions:

  • 19 + 8389 = 8408
  • 31 + 8377 = 8408
  • 79 + 8329 = 8408
  • 97 + 8311 = 8408
  • 139 + 8269 = 8408
  • 199 + 8209 = 8408
  • 229 + 8179 = 8408
  • 241 + 8167 = 8408

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8408 first appears in π at position 33,246 of the decimal expansion (the 33,246ordinal-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.
