Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41440, here are decompositions:

  • 29 + 41411 = 41440
  • 41 + 41399 = 41440
  • 53 + 41387 = 41440
  • 59 + 41381 = 41440
  • 83 + 41357 = 41440
  • 89 + 41351 = 41440
  • 107 + 41333 = 41440
  • 197 + 41243 = 41440

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 41440 first appears in π at position 154,057 of the decimal expansion (the 154,057ordinal-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.
