Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550586, here are decompositions:

5 + 31550581 = 31550586
13 + 31550573 = 31550586
17 + 31550569 = 31550586
29 + 31550557 = 31550586
43 + 31550543 = 31550586
47 + 31550539 = 31550586
107 + 31550479 = 31550586
127 + 31550459 = 31550586

Showing the first eight; more decompositions exist.
