Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550056, here are decompositions:

29 + 31550027 = 31550056
89 + 31549967 = 31550056
137 + 31549919 = 31550056
227 + 31549829 = 31550056
257 + 31549799 = 31550056
389 + 31549667 = 31550056
449 + 31549607 = 31550056
467 + 31549589 = 31550056

Showing the first eight; more decompositions exist.
