Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40450, here are decompositions:

  • 17 + 40433 = 40450
  • 23 + 40427 = 40450
  • 89 + 40361 = 40450
  • 107 + 40343 = 40450
  • 167 + 40283 = 40450
  • 173 + 40277 = 40450
  • 197 + 40253 = 40450
  • 257 + 40193 = 40450

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40450 first appears in π at position 112,710 of the decimal expansion (the 112,710ordinal-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.
