Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527942, here are decompositions:

11 + 31527931 = 31527942
29 + 31527913 = 31527942
113 + 31527829 = 31527942
233 + 31527709 = 31527942
239 + 31527703 = 31527942
241 + 31527701 = 31527942
283 + 31527659 = 31527942
359 + 31527583 = 31527942

Showing the first eight; more decompositions exist.
