Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544334, here are decompositions:

11 + 31544323 = 31544334
23 + 31544311 = 31544334
37 + 31544297 = 31544334
53 + 31544281 = 31544334
113 + 31544221 = 31544334
127 + 31544207 = 31544334
163 + 31544171 = 31544334
167 + 31544167 = 31544334

Showing the first eight; more decompositions exist.
