Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465704, here are decompositions:

7 + 31465697 = 31465704
31 + 31465673 = 31465704
41 + 31465663 = 31465704
43 + 31465661 = 31465704
73 + 31465631 = 31465704
103 + 31465601 = 31465704
157 + 31465547 = 31465704
223 + 31465481 = 31465704

Showing the first eight; more decompositions exist.
