Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450456, here are decompositions:

5 + 31450451 = 31450456
29 + 31450427 = 31450456
47 + 31450409 = 31450456
239 + 31450217 = 31450456
293 + 31450163 = 31450456
353 + 31450103 = 31450456
467 + 31449989 = 31450456
809 + 31449647 = 31450456

Showing the first eight; more decompositions exist.
