Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456362, here are decompositions:

31 + 31456331 = 31456362
43 + 31456319 = 31456362
71 + 31456291 = 31456362
83 + 31456279 = 31456362
103 + 31456259 = 31456362
163 + 31456199 = 31456362
199 + 31456163 = 31456362
239 + 31456123 = 31456362

Showing the first eight; more decompositions exist.
