Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478646, here are decompositions:

19 + 478627 = 478646
43 + 478603 = 478646
67 + 478579 = 478646
73 + 478573 = 478646
163 + 478483 = 478646
193 + 478453 = 478646
229 + 478417 = 478646
307 + 478339 = 478646

Showing the first eight; more decompositions exist.
