Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626268, here are decompositions:

59 + 31626209 = 31626268
71 + 31626197 = 31626268
101 + 31626167 = 31626268
137 + 31626131 = 31626268
227 + 31626041 = 31626268
257 + 31626011 = 31626268
281 + 31625987 = 31626268
419 + 31625849 = 31626268

Showing the first eight; more decompositions exist.
