Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519896, here are decompositions:

7 + 31519889 = 31519896
19 + 31519877 = 31519896
53 + 31519843 = 31519896
59 + 31519837 = 31519896
73 + 31519823 = 31519896
103 + 31519793 = 31519896
113 + 31519783 = 31519896
127 + 31519769 = 31519896

Showing the first eight; more decompositions exist.
