Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544310, here are decompositions:

13 + 31544297 = 31544310
29 + 31544281 = 31544310
89 + 31544221 = 31544310
97 + 31544213 = 31544310
103 + 31544207 = 31544310
131 + 31544179 = 31544310
139 + 31544171 = 31544310
157 + 31544153 = 31544310

Showing the first eight; more decompositions exist.
