Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4442, here are decompositions:

  • 19 + 4423 = 4442
  • 79 + 4363 = 4442
  • 103 + 4339 = 4442
  • 181 + 4261 = 4442
  • 199 + 4243 = 4442
  • 211 + 4231 = 4442
  • 223 + 4219 = 4442
  • 241 + 4201 = 4442

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 4442 first appears in π at position 3,476 of the decimal expansion (the 3,476ordinal-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.
