Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627506, here are decompositions:

5 + 31627501 = 31627506
23 + 31627483 = 31627506
149 + 31627357 = 31627506
173 + 31627333 = 31627506
257 + 31627249 = 31627506
263 + 31627243 = 31627506
269 + 31627237 = 31627506
373 + 31627133 = 31627506

Showing the first eight; more decompositions exist.
