Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1444, here are decompositions:

  • 5 + 1439 = 1444
  • 11 + 1433 = 1444
  • 17 + 1427 = 1444
  • 71 + 1373 = 1444
  • 83 + 1361 = 1444
  • 137 + 1307 = 1444
  • 167 + 1277 = 1444
  • 227 + 1217 = 1444

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1444 first appears in π at position 3,475 of the decimal expansion (the 3,475ordinal-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.
