Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445552, here are decompositions:

13 + 31445539 = 31445552
109 + 31445443 = 31445552
199 + 31445353 = 31445552
283 + 31445269 = 31445552
331 + 31445221 = 31445552
349 + 31445203 = 31445552
379 + 31445173 = 31445552
613 + 31444939 = 31445552

Showing the first eight; more decompositions exist.
