Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447896, here are decompositions:

43 + 31447853 = 31447896
59 + 31447837 = 31447896
83 + 31447813 = 31447896
97 + 31447799 = 31447896
113 + 31447783 = 31447896
127 + 31447769 = 31447896
223 + 31447673 = 31447896
229 + 31447667 = 31447896

Showing the first eight; more decompositions exist.
