Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493680, here are decompositions:

  • 7 + 33493673 = 33493680
  • 41 + 33493639 = 33493680
  • 53 + 33493627 = 33493680
  • 61 + 33493619 = 33493680
  • 67 + 33493613 = 33493680
  • 79 + 33493601 = 33493680
  • 89 + 33493591 = 33493680
  • 107 + 33493573 = 33493680

Showing the first eight; more decompositions exist.
