Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536942, here are decompositions:

5 + 31536937 = 31536942
71 + 31536871 = 31536942
79 + 31536863 = 31536942
113 + 31536829 = 31536942
149 + 31536793 = 31536942
211 + 31536731 = 31536942
223 + 31536719 = 31536942
313 + 31536629 = 31536942

Showing the first eight; more decompositions exist.
