Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295005640, here are decompositions:

  • 43 + 4295005597 = 4295005640
  • 73 + 4295005567 = 4295005640
  • 181 + 4295005459 = 4295005640
  • 223 + 4295005417 = 4295005640
  • 229 + 4295005411 = 4295005640
  • 271 + 4295005369 = 4295005640
  • 433 + 4295005207 = 4295005640
  • 619 + 4295005021 = 4295005640

Showing the first eight; more decompositions exist.
