Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999720, here are decompositions:

  • 3 + 4294999717 = 4294999720
  • 173 + 4294999547 = 4294999720
  • 257 + 4294999463 = 4294999720
  • 311 + 4294999409 = 4294999720
  • 587 + 4294999133 = 4294999720
  • 821 + 4294998899 = 4294999720
  • 863 + 4294998857 = 4294999720
  • 1049 + 4294998671 = 4294999720

Showing the first eight; more decompositions exist.
