Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450176, here are decompositions:

13 + 31450163 = 31450176
59 + 31450117 = 31450176
73 + 31450103 = 31450176
83 + 31450093 = 31450176
239 + 31449937 = 31450176
353 + 31449823 = 31450176
409 + 31449767 = 31450176
419 + 31449757 = 31450176

Showing the first eight; more decompositions exist.
