Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550552, here are decompositions:

13 + 31550539 = 31550552
43 + 31550509 = 31550552
73 + 31550479 = 31550552
151 + 31550401 = 31550552
181 + 31550371 = 31550552
199 + 31550353 = 31550552
223 + 31550329 = 31550552
331 + 31550221 = 31550552

Showing the first eight; more decompositions exist.
