Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450494, here are decompositions:

7 + 31450487 = 31450494
11 + 31450483 = 31450494
43 + 31450451 = 31450494
67 + 31450427 = 31450494
71 + 31450423 = 31450494
73 + 31450421 = 31450494
83 + 31450411 = 31450494
107 + 31450387 = 31450494

Showing the first eight; more decompositions exist.
