Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42562, here are decompositions:

  • 5 + 42557 = 42562
  • 29 + 42533 = 42562
  • 53 + 42509 = 42562
  • 71 + 42491 = 42562
  • 89 + 42473 = 42562
  • 101 + 42461 = 42562
  • 239 + 42323 = 42562
  • 263 + 42299 = 42562

Showing the first eight; more decompositions exist.
