Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450466, here are decompositions:

37 + 31450429 = 31450466
43 + 31450423 = 31450466
79 + 31450387 = 31450466
97 + 31450369 = 31450466
349 + 31450117 = 31450466
367 + 31450099 = 31450466
373 + 31450093 = 31450466
409 + 31450057 = 31450466

Showing the first eight; more decompositions exist.
