Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40436, here are decompositions:

  • 3 + 40433 = 40436
  • 7 + 40429 = 40436
  • 13 + 40423 = 40436
  • 79 + 40357 = 40436
  • 199 + 40237 = 40436
  • 223 + 40213 = 40436
  • 283 + 40153 = 40436
  • 307 + 40129 = 40436

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40436 first appears in π at position 42,160 of the decimal expansion (the 42,160ordinal-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.
