Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43472, here are decompositions:

  • 31 + 43441 = 43472
  • 61 + 43411 = 43472
  • 73 + 43399 = 43472
  • 151 + 43321 = 43472
  • 181 + 43291 = 43472
  • 211 + 43261 = 43472
  • 271 + 43201 = 43472
  • 283 + 43189 = 43472

Showing the first eight; more decompositions exist.
