Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626292, here are decompositions:

59 + 31626233 = 31626292
83 + 31626209 = 31626292
101 + 31626191 = 31626292
239 + 31626053 = 31626292
251 + 31626041 = 31626292
281 + 31626011 = 31626292
311 + 31625981 = 31626292
353 + 31625939 = 31626292

Showing the first eight; more decompositions exist.
