Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515832, here are decompositions:

  • 19 + 515813 = 515832
  • 29 + 515803 = 515832
  • 59 + 515773 = 515832
  • 61 + 515771 = 515832
  • 71 + 515761 = 515832
  • 131 + 515701 = 515832
  • 139 + 515693 = 515832
  • 151 + 515681 = 515832

Showing the first eight; more decompositions exist.
