Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527308, here are decompositions:

31 + 31527277 = 31527308
61 + 31527247 = 31527308
97 + 31527211 = 31527308
151 + 31527157 = 31527308
157 + 31527151 = 31527308
199 + 31527109 = 31527308
367 + 31526941 = 31527308
409 + 31526899 = 31527308

Showing the first eight; more decompositions exist.
