Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624472, here are decompositions:

  • 43 + 31624429 = 31624472
  • 109 + 31624363 = 31624472
  • 151 + 31624321 = 31624472
  • 331 + 31624141 = 31624472
  • 541 + 31623931 = 31624472
  • 571 + 31623901 = 31624472
  • 751 + 31623721 = 31624472
  • 769 + 31623703 = 31624472

Showing the first eight; more decompositions exist.
