Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468778, here are decompositions:

5 + 468773 = 468778
17 + 468761 = 468778
41 + 468737 = 468778
59 + 468719 = 468778
131 + 468647 = 468778
137 + 468641 = 468778
179 + 468599 = 468778
197 + 468581 = 468778

Showing the first eight; more decompositions exist.
