Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43646, here are decompositions:

13 + 43633 = 43646
19 + 43627 = 43646
37 + 43609 = 43646
67 + 43579 = 43646
73 + 43573 = 43646
103 + 43543 = 43646
409 + 43237 = 43646
439 + 43207 = 43646

Showing the first eight; more decompositions exist.
