Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508352, here are decompositions:

  • 23 + 31508329 = 31508352
  • 41 + 31508311 = 31508352
  • 149 + 31508203 = 31508352
  • 173 + 31508179 = 31508352
  • 181 + 31508171 = 31508352
  • 193 + 31508159 = 31508352
  • 199 + 31508153 = 31508352
  • 233 + 31508119 = 31508352

Showing the first eight; more decompositions exist.
