Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626300, here are decompositions:

53 + 31626247 = 31626300
67 + 31626233 = 31626300
71 + 31626229 = 31626300
103 + 31626197 = 31626300
107 + 31626193 = 31626300
109 + 31626191 = 31626300
191 + 31626109 = 31626300
227 + 31626073 = 31626300

Showing the first eight; more decompositions exist.
