Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4380, here are decompositions:

  • 7 + 4373 = 4380
  • 17 + 4363 = 4380
  • 23 + 4357 = 4380
  • 31 + 4349 = 4380
  • 41 + 4339 = 4380
  • 43 + 4337 = 4380
  • 53 + 4327 = 4380
  • 83 + 4297 = 4380

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 4380 first appears in π at position 15,453 of the decimal expansion (the 15,453ordinal-suffix:rd 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.
