Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295018640, here are decompositions:

  • 7 + 4295018633 = 4295018640
  • 41 + 4295018599 = 4295018640
  • 47 + 4295018593 = 4295018640
  • 67 + 4295018573 = 4295018640
  • 71 + 4295018569 = 4295018640
  • 79 + 4295018561 = 4295018640
  • 137 + 4295018503 = 4295018640
  • 139 + 4295018501 = 4295018640

Showing the first eight; more decompositions exist.
