Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626502, here are decompositions:

3 + 31626499 = 31626502
41 + 31626461 = 31626502
113 + 31626389 = 31626502
179 + 31626323 = 31626502
269 + 31626233 = 31626502
293 + 31626209 = 31626502
311 + 31626191 = 31626502
449 + 31626053 = 31626502

Showing the first eight; more decompositions exist.
