Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462896, here are decompositions:

7 + 31462889 = 31462896
19 + 31462877 = 31462896
89 + 31462807 = 31462896
103 + 31462793 = 31462896
137 + 31462759 = 31462896
139 + 31462757 = 31462896
149 + 31462747 = 31462896
167 + 31462729 = 31462896

Showing the first eight; more decompositions exist.
