Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482942, here are decompositions:

53 + 31482889 = 31482942
83 + 31482859 = 31482942
103 + 31482839 = 31482942
109 + 31482833 = 31482942
163 + 31482779 = 31482942
181 + 31482761 = 31482942
199 + 31482743 = 31482942
233 + 31482709 = 31482942

Showing the first eight; more decompositions exist.
