Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456174, here are decompositions:

11 + 31456163 = 31456174
53 + 31456121 = 31456174
107 + 31456067 = 31456174
227 + 31455947 = 31456174
353 + 31455821 = 31456174
461 + 31455713 = 31456174
641 + 31455533 = 31456174
653 + 31455521 = 31456174

Showing the first eight; more decompositions exist.
