Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10380, here are decompositions:

  • 11 + 10369 = 10380
  • 23 + 10357 = 10380
  • 37 + 10343 = 10380
  • 43 + 10337 = 10380
  • 47 + 10333 = 10380
  • 59 + 10321 = 10380
  • 67 + 10313 = 10380
  • 79 + 10301 = 10380

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10380 first appears in π at position 333,260 of the decimal expansion (the 333,260ordinal-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.
