Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544372, here are decompositions:

  • 3 + 33544369 = 33544372
  • 41 + 33544331 = 33544372
  • 149 + 33544223 = 33544372
  • 293 + 33544079 = 33544372
  • 359 + 33544013 = 33544372
  • 401 + 33543971 = 33544372
  • 443 + 33543929 = 33544372
  • 569 + 33543803 = 33544372

Showing the first eight; more decompositions exist.
