Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600758, here are decompositions:

5 + 31600753 = 31600758
17 + 31600741 = 31600758
37 + 31600721 = 31600758
41 + 31600717 = 31600758
89 + 31600669 = 31600758
139 + 31600619 = 31600758
227 + 31600531 = 31600758
229 + 31600529 = 31600758

Showing the first eight; more decompositions exist.
