Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626202, here are decompositions:

5 + 31626197 = 31626202
11 + 31626191 = 31626202
71 + 31626131 = 31626202
149 + 31626053 = 31626202
191 + 31626011 = 31626202
233 + 31625969 = 31626202
239 + 31625963 = 31626202
263 + 31625939 = 31626202

Showing the first eight; more decompositions exist.
