Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542966, here are decompositions:

17 + 31542949 = 31542966
23 + 31542943 = 31542966
29 + 31542937 = 31542966
89 + 31542877 = 31542966
109 + 31542857 = 31542966
137 + 31542829 = 31542966
139 + 31542827 = 31542966
157 + 31542809 = 31542966

Showing the first eight; more decompositions exist.
