Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450474, here are decompositions:

23 + 31450451 = 31450474
47 + 31450427 = 31450474
53 + 31450421 = 31450474
227 + 31450247 = 31450474
257 + 31450217 = 31450474
311 + 31450163 = 31450474
431 + 31450043 = 31450474
443 + 31450031 = 31450474

Showing the first eight; more decompositions exist.
