Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523444, here are decompositions:

  • 3 + 31523441 = 31523444
  • 37 + 31523407 = 31523444
  • 97 + 31523347 = 31523444
  • 151 + 31523293 = 31523444
  • 193 + 31523251 = 31523444
  • 223 + 31523221 = 31523444
  • 283 + 31523161 = 31523444
  • 313 + 31523131 = 31523444

Showing the first eight; more decompositions exist.
