Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458996, here are decompositions:

13 + 31458983 = 31458996
29 + 31458967 = 31458996
43 + 31458953 = 31458996
59 + 31458937 = 31458996
73 + 31458923 = 31458996
83 + 31458913 = 31458996
89 + 31458907 = 31458996
167 + 31458829 = 31458996

Showing the first eight; more decompositions exist.
