Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550648, here are decompositions:

37 + 31550611 = 31550648
61 + 31550587 = 31550648
67 + 31550581 = 31550648
79 + 31550569 = 31550648
109 + 31550539 = 31550648
139 + 31550509 = 31550648
211 + 31550437 = 31550648
277 + 31550371 = 31550648

Showing the first eight; more decompositions exist.
