Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500364, here are decompositions:

3 + 31500361 = 31500364
11 + 31500353 = 31500364
83 + 31500281 = 31500364
101 + 31500263 = 31500364
167 + 31500197 = 31500364
251 + 31500113 = 31500364
257 + 31500107 = 31500364
263 + 31500101 = 31500364

Showing the first eight; more decompositions exist.
