Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552316, here are decompositions:

7 + 31552309 = 31552316
13 + 31552303 = 31552316
79 + 31552237 = 31552316
109 + 31552207 = 31552316
283 + 31552033 = 31552316
337 + 31551979 = 31552316
379 + 31551937 = 31552316
457 + 31551859 = 31552316

Showing the first eight; more decompositions exist.
