Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546806, here are decompositions:

7 + 31546799 = 31546806
17 + 31546789 = 31546806
47 + 31546759 = 31546806
89 + 31546717 = 31546806
97 + 31546709 = 31546806
149 + 31546657 = 31546806
173 + 31546633 = 31546806
223 + 31546583 = 31546806

Showing the first eight; more decompositions exist.
