Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542882, here are decompositions:

5 + 31542877 = 31542882
53 + 31542829 = 31542882
71 + 31542811 = 31542882
73 + 31542809 = 31542882
83 + 31542799 = 31542882
179 + 31542703 = 31542882
223 + 31542659 = 31542882
251 + 31542631 = 31542882

Showing the first eight; more decompositions exist.
