Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295001640, here are decompositions:

  • 179 + 4295001461 = 4295001640
  • 353 + 4295001287 = 4295001640
  • 389 + 4295001251 = 4295001640
  • 443 + 4295001197 = 4295001640
  • 491 + 4295001149 = 4295001640
  • 509 + 4295001131 = 4295001640
  • 563 + 4295001077 = 4295001640
  • 653 + 4295000987 = 4295001640

Showing the first eight; more decompositions exist.
