Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542828, here are decompositions:

17 + 31542811 = 31542828
19 + 31542809 = 31542828
29 + 31542799 = 31542828
41 + 31542787 = 31542828
61 + 31542767 = 31542828
101 + 31542727 = 31542828
131 + 31542697 = 31542828
151 + 31542677 = 31542828

Showing the first eight; more decompositions exist.
