Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626274, here are decompositions:

41 + 31626233 = 31626274
83 + 31626191 = 31626274
107 + 31626167 = 31626274
233 + 31626041 = 31626274
263 + 31626011 = 31626274
293 + 31625981 = 31626274
311 + 31625963 = 31626274
431 + 31625843 = 31626274

Showing the first eight; more decompositions exist.
