Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61542, here are decompositions:

  • 23 + 61519 = 61542
  • 31 + 61511 = 61542
  • 59 + 61483 = 61542
  • 71 + 61471 = 61542
  • 73 + 61469 = 61542
  • 79 + 61463 = 61542
  • 101 + 61441 = 61542
  • 139 + 61403 = 61542

Showing the first eight; more decompositions exist.
