Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456710, here are decompositions:

7 + 31456703 = 31456710
31 + 31456679 = 31456710
41 + 31456669 = 31456710
59 + 31456651 = 31456710
71 + 31456639 = 31456710
113 + 31456597 = 31456710
163 + 31456547 = 31456710
179 + 31456531 = 31456710

Showing the first eight; more decompositions exist.
