Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76420, here are decompositions:

  • 17 + 76403 = 76420
  • 41 + 76379 = 76420
  • 53 + 76367 = 76420
  • 131 + 76289 = 76420
  • 137 + 76283 = 76420
  • 167 + 76253 = 76420
  • 257 + 76163 = 76420
  • 263 + 76157 = 76420

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 76420 first appears in π at position 45,454 of the decimal expansion (the 45,454ordinal-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.
