Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991720, here are decompositions:

  • 7 + 4294991713 = 4294991720
  • 43 + 4294991677 = 4294991720
  • 67 + 4294991653 = 4294991720
  • 163 + 4294991557 = 4294991720
  • 181 + 4294991539 = 4294991720
  • 199 + 4294991521 = 4294991720
  • 211 + 4294991509 = 4294991720
  • 223 + 4294991497 = 4294991720

Showing the first eight; more decompositions exist.
