Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470778, here are decompositions:

29 + 470749 = 470778
47 + 470731 = 470778
59 + 470719 = 470778
67 + 470711 = 470778
89 + 470689 = 470778
109 + 470669 = 470778
127 + 470651 = 470778
131 + 470647 = 470778

Showing the first eight; more decompositions exist.
