Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559108, here are decompositions:

37 + 31559071 = 31559108
151 + 31558957 = 31559108
181 + 31558927 = 31559108
211 + 31558897 = 31559108
277 + 31558831 = 31559108
337 + 31558771 = 31559108
349 + 31558759 = 31559108
367 + 31558741 = 31559108

Showing the first eight; more decompositions exist.
