Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450896, here are decompositions:

5 + 31450891 = 31450896
17 + 31450879 = 31450896
53 + 31450843 = 31450896
67 + 31450829 = 31450896
73 + 31450823 = 31450896
107 + 31450789 = 31450896
109 + 31450787 = 31450896
157 + 31450739 = 31450896

Showing the first eight; more decompositions exist.
