Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470838, here are decompositions:

7 + 470831 = 470838
19 + 470819 = 470838
47 + 470791 = 470838
59 + 470779 = 470838
89 + 470749 = 470838
107 + 470731 = 470838
127 + 470711 = 470838
149 + 470689 = 470838

Showing the first eight; more decompositions exist.
