Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626190, here are decompositions:

23 + 31626167 = 31626190
59 + 31626131 = 31626190
137 + 31626053 = 31626190
149 + 31626041 = 31626190
179 + 31626011 = 31626190
227 + 31625963 = 31626190
251 + 31625939 = 31626190
347 + 31625843 = 31626190

Showing the first eight; more decompositions exist.
