Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992720, here are decompositions:

  • 17 + 4294992703 = 4294992720
  • 37 + 4294992683 = 4294992720
  • 43 + 4294992677 = 4294992720
  • 59 + 4294992661 = 4294992720
  • 173 + 4294992547 = 4294992720
  • 257 + 4294992463 = 4294992720
  • 281 + 4294992439 = 4294992720
  • 307 + 4294992413 = 4294992720

Showing the first eight; more decompositions exist.
