Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550300, here are decompositions:

13 + 31550287 = 31550300
43 + 31550257 = 31550300
79 + 31550221 = 31550300
151 + 31550149 = 31550300
163 + 31550137 = 31550300
181 + 31550119 = 31550300
193 + 31550107 = 31550300
337 + 31549963 = 31550300

Showing the first eight; more decompositions exist.
