Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550484, here are decompositions:

5 + 31550479 = 31550484
13 + 31550471 = 31550484
23 + 31550461 = 31550484
37 + 31550447 = 31550484
47 + 31550437 = 31550484
83 + 31550401 = 31550484
113 + 31550371 = 31550484
127 + 31550357 = 31550484

Showing the first eight; more decompositions exist.
