Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449896, here are decompositions:

43 + 31449853 = 31449896
73 + 31449823 = 31449896
139 + 31449757 = 31449896
157 + 31449739 = 31449896
199 + 31449697 = 31449896
223 + 31449673 = 31449896
277 + 31449619 = 31449896
307 + 31449589 = 31449896

Showing the first eight; more decompositions exist.
