Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542950, here are decompositions:

7 + 31542943 = 31542950
13 + 31542937 = 31542950
73 + 31542877 = 31542950
139 + 31542811 = 31542950
151 + 31542799 = 31542950
163 + 31542787 = 31542950
223 + 31542727 = 31542950
337 + 31542613 = 31542950

Showing the first eight; more decompositions exist.
