Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450600, here are decompositions:

11 + 31450589 = 31450600
17 + 31450583 = 31450600
23 + 31450577 = 31450600
59 + 31450541 = 31450600
113 + 31450487 = 31450600
149 + 31450451 = 31450600
173 + 31450427 = 31450600
179 + 31450421 = 31450600

Showing the first eight; more decompositions exist.
