Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609084, here are decompositions:

  • 5 + 31609079 = 31609084
  • 53 + 31609031 = 31609084
  • 113 + 31608971 = 31609084
  • 131 + 31608953 = 31609084
  • 167 + 31608917 = 31609084
  • 173 + 31608911 = 31609084
  • 191 + 31608893 = 31609084
  • 197 + 31608887 = 31609084

Showing the first eight; more decompositions exist.
