Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450594, here are decompositions:

5 + 31450589 = 31450594
11 + 31450583 = 31450594
17 + 31450577 = 31450594
53 + 31450541 = 31450594
107 + 31450487 = 31450594
167 + 31450427 = 31450594
173 + 31450421 = 31450594
281 + 31450313 = 31450594

Showing the first eight; more decompositions exist.
