Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559048, here are decompositions:

109 + 31558939 = 31559048
151 + 31558897 = 31559048
229 + 31558819 = 31559048
277 + 31558771 = 31559048
307 + 31558741 = 31559048
331 + 31558717 = 31559048
421 + 31558627 = 31559048
727 + 31558321 = 31559048

Showing the first eight; more decompositions exist.
