Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724986, here are decompositions:

  • 3 + 8724983 = 8724986
  • 19 + 8724967 = 8724986
  • 37 + 8724949 = 8724986
  • 43 + 8724943 = 8724986
  • 103 + 8724883 = 8724986
  • 139 + 8724847 = 8724986
  • 199 + 8724787 = 8724986
  • 337 + 8724649 = 8724986

Showing the first eight; more decompositions exist.
