Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626046, here are decompositions:

5 + 31626041 = 31626046
59 + 31625987 = 31626046
83 + 31625963 = 31626046
107 + 31625939 = 31626046
197 + 31625849 = 31626046
227 + 31625819 = 31626046
239 + 31625807 = 31626046
269 + 31625777 = 31626046

Showing the first eight; more decompositions exist.
