Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109440, here are decompositions:

  • 7 + 109433 = 109440
  • 17 + 109423 = 109440
  • 43 + 109397 = 109440
  • 53 + 109387 = 109440
  • 61 + 109379 = 109440
  • 73 + 109367 = 109440
  • 83 + 109357 = 109440
  • 109 + 109331 = 109440

Showing the first eight; more decompositions exist.
