Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550576, here are decompositions:

3 + 31550573 = 31550576
7 + 31550569 = 31550576
19 + 31550557 = 31550576
37 + 31550539 = 31550576
67 + 31550509 = 31550576
97 + 31550479 = 31550576
139 + 31550437 = 31550576
223 + 31550353 = 31550576

Showing the first eight; more decompositions exist.
