Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295072688, here are decompositions:

  • 7 + 4295072681 = 4295072688
  • 19 + 4295072669 = 4295072688
  • 79 + 4295072609 = 4295072688
  • 199 + 4295072489 = 4295072688
  • 211 + 4295072477 = 4295072688
  • 251 + 4295072437 = 4295072688
  • 419 + 4295072269 = 4295072688
  • 421 + 4295072267 = 4295072688

Showing the first eight; more decompositions exist.
