Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295072638, here are decompositions:

  • 29 + 4295072609 = 4295072638
  • 41 + 4295072597 = 4295072638
  • 149 + 4295072489 = 4295072638
  • 251 + 4295072387 = 4295072638
  • 431 + 4295072207 = 4295072638
  • 557 + 4295072081 = 4295072638
  • 569 + 4295072069 = 4295072638
  • 641 + 4295071997 = 4295072638

Showing the first eight; more decompositions exist.
