Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471622, here are decompositions:

  • 31 + 31471591 = 31471622
  • 43 + 31471579 = 31471622
  • 73 + 31471549 = 31471622
  • 211 + 31471411 = 31471622
  • 409 + 31471213 = 31471622
  • 499 + 31471123 = 31471622
  • 571 + 31471051 = 31471622
  • 631 + 31470991 = 31471622

Showing the first eight; more decompositions exist.
