Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626492, here are decompositions:

11 + 31626481 = 31626492
31 + 31626461 = 31626492
71 + 31626421 = 31626492
103 + 31626389 = 31626492
109 + 31626383 = 31626492
263 + 31626229 = 31626492
283 + 31626209 = 31626492
383 + 31626109 = 31626492

Showing the first eight; more decompositions exist.
