Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627374, here are decompositions:

17 + 31627357 = 31627374
41 + 31627333 = 31627374
71 + 31627303 = 31627374
113 + 31627261 = 31627374
127 + 31627247 = 31627374
131 + 31627243 = 31627374
137 + 31627237 = 31627374
157 + 31627217 = 31627374

Showing the first eight; more decompositions exist.
