Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64436, here are decompositions:

  • 3 + 64433 = 64436
  • 37 + 64399 = 64436
  • 103 + 64333 = 64436
  • 109 + 64327 = 64436
  • 157 + 64279 = 64436
  • 199 + 64237 = 64436
  • 283 + 64153 = 64436
  • 313 + 64123 = 64436

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64436 first appears in π at position 180,311 of the decimal expansion (the 180,311ordinal-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.
