Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487760, here are decompositions:

  • 3 + 33487757 = 33487760
  • 43 + 33487717 = 33487760
  • 79 + 33487681 = 33487760
  • 109 + 33487651 = 33487760
  • 139 + 33487621 = 33487760
  • 181 + 33487579 = 33487760
  • 199 + 33487561 = 33487760
  • 223 + 33487537 = 33487760

Showing the first eight; more decompositions exist.
