Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606080, here are decompositions:

  • 13 + 31606067 = 31606080
  • 19 + 31606061 = 31606080
  • 29 + 31606051 = 31606080
  • 31 + 31606049 = 31606080
  • 97 + 31605983 = 31606080
  • 109 + 31605971 = 31606080
  • 127 + 31605953 = 31606080
  • 151 + 31605929 = 31606080

Showing the first eight; more decompositions exist.
