Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51708, here are decompositions:

  • 17 + 51691 = 51708
  • 29 + 51679 = 51708
  • 61 + 51647 = 51708
  • 71 + 51637 = 51708
  • 101 + 51607 = 51708
  • 109 + 51599 = 51708
  • 127 + 51581 = 51708
  • 131 + 51577 = 51708

Showing the first eight; more decompositions exist.
