Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527314, here are decompositions:

3 + 31527311 = 31527314
37 + 31527277 = 31527314
61 + 31527253 = 31527314
67 + 31527247 = 31527314
103 + 31527211 = 31527314
157 + 31527157 = 31527314
163 + 31527151 = 31527314
373 + 31526941 = 31527314

Showing the first eight; more decompositions exist.
