Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39646, here are decompositions:

23 + 39623 = 39646
83 + 39563 = 39646
137 + 39509 = 39646
227 + 39419 = 39646
263 + 39383 = 39646
353 + 39293 = 39646
419 + 39227 = 39646
557 + 39089 = 39646

Showing the first eight; more decompositions exist.
