Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550694, here are decompositions:

13 + 31550681 = 31550694
23 + 31550671 = 31550694
67 + 31550627 = 31550694
83 + 31550611 = 31550694
101 + 31550593 = 31550694
107 + 31550587 = 31550694
113 + 31550581 = 31550694
137 + 31550557 = 31550694

Showing the first eight; more decompositions exist.
