Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627250, here are decompositions:

3 + 31627247 = 31627250
7 + 31627243 = 31627250
13 + 31627237 = 31627250
181 + 31627069 = 31627250
199 + 31627051 = 31627250
223 + 31627027 = 31627250
271 + 31626979 = 31627250
283 + 31626967 = 31627250

Showing the first eight; more decompositions exist.
