Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624224, here are decompositions:

  • 7 + 31624217 = 31624224
  • 83 + 31624141 = 31624224
  • 97 + 31624127 = 31624224
  • 211 + 31624013 = 31624224
  • 223 + 31624001 = 31624224
  • 241 + 31623983 = 31624224
  • 257 + 31623967 = 31624224
  • 271 + 31623953 = 31624224

Showing the first eight; more decompositions exist.
