Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537276, here are decompositions:

3 + 31537273 = 31537276
5 + 31537271 = 31537276
47 + 31537229 = 31537276
53 + 31537223 = 31537276
149 + 31537127 = 31537276
179 + 31537097 = 31537276
227 + 31537049 = 31537276
233 + 31537043 = 31537276

Showing the first eight; more decompositions exist.
