Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542846, here are decompositions:

17 + 31542829 = 31542846
19 + 31542827 = 31542846
37 + 31542809 = 31542846
47 + 31542799 = 31542846
59 + 31542787 = 31542846
79 + 31542767 = 31542846
149 + 31542697 = 31542846
233 + 31542613 = 31542846

Showing the first eight; more decompositions exist.
