Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40634, here are decompositions:

  • 7 + 40627 = 40634
  • 37 + 40597 = 40634
  • 43 + 40591 = 40634
  • 103 + 40531 = 40634
  • 127 + 40507 = 40634
  • 151 + 40483 = 40634
  • 163 + 40471 = 40634
  • 211 + 40423 = 40634

Showing the first eight; more decompositions exist.
