Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546566, here are decompositions:

13 + 31546553 = 31546566
83 + 31546483 = 31546566
97 + 31546469 = 31546566
109 + 31546457 = 31546566
173 + 31546393 = 31546566
179 + 31546387 = 31546566
197 + 31546369 = 31546566
229 + 31546337 = 31546566

Showing the first eight; more decompositions exist.
