Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450826, here are decompositions:

3 + 31450823 = 31450826
37 + 31450789 = 31450826
103 + 31450723 = 31450826
223 + 31450603 = 31450826
283 + 31450543 = 31450826
397 + 31450429 = 31450826
439 + 31450387 = 31450826
457 + 31450369 = 31450826

Showing the first eight; more decompositions exist.
