Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295002640, here are decompositions:

  • 3 + 4295002637 = 4295002640
  • 7 + 4295002633 = 4295002640
  • 31 + 4295002609 = 4295002640
  • 37 + 4295002603 = 4295002640
  • 43 + 4295002597 = 4295002640
  • 139 + 4295002501 = 4295002640
  • 199 + 4295002441 = 4295002640
  • 211 + 4295002429 = 4295002640

Showing the first eight; more decompositions exist.
