Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76400, here are decompositions:

  • 13 + 76387 = 76400
  • 31 + 76369 = 76400
  • 67 + 76333 = 76400
  • 97 + 76303 = 76400
  • 139 + 76261 = 76400
  • 151 + 76249 = 76400
  • 157 + 76243 = 76400
  • 193 + 76207 = 76400

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 76400 first appears in π at position 37,319 of the decimal expansion (the 37,319ordinal-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.
