Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546666, here are decompositions:

3 + 31546663 = 31546666
5 + 31546661 = 31546666
29 + 31546637 = 31546666
83 + 31546583 = 31546666
113 + 31546553 = 31546666
197 + 31546469 = 31546666
317 + 31546349 = 31546666
383 + 31546283 = 31546666

Showing the first eight; more decompositions exist.
