Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450588, here are decompositions:

5 + 31450583 = 31450588
11 + 31450577 = 31450588
47 + 31450541 = 31450588
101 + 31450487 = 31450588
137 + 31450451 = 31450588
167 + 31450421 = 31450588
179 + 31450409 = 31450588
317 + 31450271 = 31450588

Showing the first eight; more decompositions exist.
