Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450634, here are decompositions:

13 + 31450621 = 31450634
31 + 31450603 = 31450634
151 + 31450483 = 31450634
211 + 31450423 = 31450634
223 + 31450411 = 31450634
283 + 31450351 = 31450634
541 + 31450093 = 31450634
577 + 31450057 = 31450634

Showing the first eight; more decompositions exist.
