Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456354, here are decompositions:

23 + 31456331 = 31456354
107 + 31456247 = 31456354
113 + 31456241 = 31456354
191 + 31456163 = 31456354
233 + 31456121 = 31456354
593 + 31455761 = 31456354
641 + 31455713 = 31456354
653 + 31455701 = 31456354

Showing the first eight; more decompositions exist.
