Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511352, here are decompositions:

11 + 31511341 = 31511352
31 + 31511321 = 31511352
71 + 31511281 = 31511352
139 + 31511213 = 31511352
163 + 31511189 = 31511352
181 + 31511171 = 31511352
211 + 31511141 = 31511352
241 + 31511111 = 31511352

Showing the first eight; more decompositions exist.
