Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544304, here are decompositions:

7 + 31544297 = 31544304
23 + 31544281 = 31544304
83 + 31544221 = 31544304
97 + 31544207 = 31544304
137 + 31544167 = 31544304
151 + 31544153 = 31544304
173 + 31544131 = 31544304
227 + 31544077 = 31544304

Showing the first eight; more decompositions exist.
