Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465306, here are decompositions:

17 + 31465289 = 31465306
83 + 31465223 = 31465306
113 + 31465193 = 31465306
359 + 31464947 = 31465306
479 + 31464827 = 31465306
797 + 31464509 = 31465306
863 + 31464443 = 31465306
947 + 31464359 = 31465306

Showing the first eight; more decompositions exist.
