Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522194, here are decompositions:

  • 13 + 31522181 = 31522194
  • 103 + 31522091 = 31522194
  • 173 + 31522021 = 31522194
  • 181 + 31522013 = 31522194
  • 241 + 31521953 = 31522194
  • 307 + 31521887 = 31522194
  • 311 + 31521883 = 31522194
  • 331 + 31521863 = 31522194

Showing the first eight; more decompositions exist.
