Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40434, here are decompositions:

  • 5 + 40429 = 40434
  • 7 + 40427 = 40434
  • 11 + 40423 = 40434
  • 47 + 40387 = 40434
  • 73 + 40361 = 40434
  • 83 + 40351 = 40434
  • 151 + 40283 = 40434
  • 157 + 40277 = 40434

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40434 first appears in π at position 66,340 of the decimal expansion (the 66,340ordinal-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.
