Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626234, here are decompositions:

5 + 31626229 = 31626234
37 + 31626197 = 31626234
41 + 31626193 = 31626234
43 + 31626191 = 31626234
67 + 31626167 = 31626234
103 + 31626131 = 31626234
181 + 31626053 = 31626234
193 + 31626041 = 31626234

Showing the first eight; more decompositions exist.
