Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546788, here are decompositions:

29 + 31546759 = 31546788
47 + 31546741 = 31546788
67 + 31546721 = 31546788
71 + 31546717 = 31546788
79 + 31546709 = 31546788
127 + 31546661 = 31546788
131 + 31546657 = 31546788
151 + 31546637 = 31546788

Showing the first eight; more decompositions exist.
