Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609826, here are decompositions:

  • 7 + 31609819 = 31609826
  • 13 + 31609813 = 31609826
  • 67 + 31609759 = 31609826
  • 103 + 31609723 = 31609826
  • 277 + 31609549 = 31609826
  • 307 + 31609519 = 31609826
  • 373 + 31609453 = 31609826
  • 433 + 31609393 = 31609826

Showing the first eight; more decompositions exist.
