Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609222, here are decompositions:

  • 131 + 31609091 = 31609222
  • 173 + 31609049 = 31609222
  • 191 + 31609031 = 31609222
  • 251 + 31608971 = 31609222
  • 263 + 31608959 = 31609222
  • 269 + 31608953 = 31609222
  • 311 + 31608911 = 31609222
  • 401 + 31608821 = 31609222

Showing the first eight; more decompositions exist.
