Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56530, here are decompositions:

  • 3 + 56527 = 56530
  • 11 + 56519 = 56530
  • 29 + 56501 = 56530
  • 41 + 56489 = 56530
  • 53 + 56477 = 56530
  • 113 + 56417 = 56530
  • 137 + 56393 = 56530
  • 197 + 56333 = 56530

Showing the first eight; more decompositions exist.
