Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449956, here are decompositions:

19 + 31449937 = 31449956
103 + 31449853 = 31449956
199 + 31449757 = 31449956
277 + 31449679 = 31449956
283 + 31449673 = 31449956
337 + 31449619 = 31449956
367 + 31449589 = 31449956
379 + 31449577 = 31449956

Showing the first eight; more decompositions exist.
