Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546646, here are decompositions:

13 + 31546633 = 31546646
73 + 31546573 = 31546646
163 + 31546483 = 31546646
277 + 31546369 = 31546646
367 + 31546279 = 31546646
379 + 31546267 = 31546646
487 + 31546159 = 31546646
577 + 31546069 = 31546646

Showing the first eight; more decompositions exist.
