Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5642, here are decompositions:

  • 3 + 5639 = 5642
  • 19 + 5623 = 5642
  • 61 + 5581 = 5642
  • 73 + 5569 = 5642
  • 79 + 5563 = 5642
  • 139 + 5503 = 5642
  • 163 + 5479 = 5642
  • 193 + 5449 = 5642

Showing the first eight; more decompositions exist.
