Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4392, here are decompositions:

  • 19 + 4373 = 4392
  • 29 + 4363 = 4392
  • 43 + 4349 = 4392
  • 53 + 4339 = 4392
  • 103 + 4289 = 4392
  • 109 + 4283 = 4392
  • 131 + 4261 = 4392
  • 139 + 4253 = 4392

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 4392 first appears in π at position 23,448 of the decimal expansion (the 23,448ordinal-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.
