Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546948, here are decompositions:

11 + 31546937 = 31546948
101 + 31546847 = 31546948
131 + 31546817 = 31546948
149 + 31546799 = 31546948
227 + 31546721 = 31546948
239 + 31546709 = 31546948
311 + 31546637 = 31546948
347 + 31546601 = 31546948

Showing the first eight; more decompositions exist.
