Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478766, here are decompositions:

3 + 478763 = 478766
19 + 478747 = 478766
37 + 478729 = 478766
139 + 478627 = 478766
163 + 478603 = 478766
193 + 478573 = 478766
283 + 478483 = 478766
307 + 478459 = 478766

Showing the first eight; more decompositions exist.
