Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456108, here are decompositions:

29 + 31456079 = 31456108
41 + 31456067 = 31456108
149 + 31455959 = 31456108
179 + 31455929 = 31456108
239 + 31455869 = 31456108
347 + 31455761 = 31456108
461 + 31455647 = 31456108
587 + 31455521 = 31456108

Showing the first eight; more decompositions exist.
