Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550482, here are decompositions:

3 + 31550479 = 31550482
11 + 31550471 = 31550482
23 + 31550459 = 31550482
269 + 31550213 = 31550482
281 + 31550201 = 31550482
389 + 31550093 = 31550482
419 + 31550063 = 31550482
461 + 31550021 = 31550482

Showing the first eight; more decompositions exist.
