Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51630, here are decompositions:

  • 17 + 51613 = 51630
  • 23 + 51607 = 51630
  • 31 + 51599 = 51630
  • 37 + 51593 = 51630
  • 53 + 51577 = 51630
  • 67 + 51563 = 51630
  • 79 + 51551 = 51630
  • 109 + 51521 = 51630

Showing the first eight; more decompositions exist.
