Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542116, here are decompositions:

3 + 31542113 = 31542116
13 + 31542103 = 31542116
79 + 31542037 = 31542116
103 + 31542013 = 31542116
127 + 31541989 = 31542116
139 + 31541977 = 31542116
223 + 31541893 = 31542116
379 + 31541737 = 31542116

Showing the first eight; more decompositions exist.
