Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469646, here are decompositions:

19 + 469627 = 469646
103 + 469543 = 469646
277 + 469369 = 469646
283 + 469363 = 469646
367 + 469279 = 469646
379 + 469267 = 469646
409 + 469237 = 469646
439 + 469207 = 469646

Showing the first eight; more decompositions exist.
