Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626342, here are decompositions:

5 + 31626337 = 31626342
19 + 31626323 = 31626342
109 + 31626233 = 31626342
113 + 31626229 = 31626342
149 + 31626193 = 31626342
151 + 31626191 = 31626342
211 + 31626131 = 31626342
233 + 31626109 = 31626342

Showing the first eight; more decompositions exist.
