Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295026640, here are decompositions:

  • 7 + 4295026633 = 4295026640
  • 43 + 4295026597 = 4295026640
  • 97 + 4295026543 = 4295026640
  • 103 + 4295026537 = 4295026640
  • 181 + 4295026459 = 4295026640
  • 193 + 4295026447 = 4295026640
  • 199 + 4295026441 = 4295026640
  • 271 + 4295026369 = 4295026640

Showing the first eight; more decompositions exist.
