Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470802, here are decompositions:

11 + 470791 = 470802
19 + 470783 = 470802
23 + 470779 = 470802
53 + 470749 = 470802
71 + 470731 = 470802
83 + 470719 = 470802
113 + 470689 = 470802
139 + 470663 = 470802

Showing the first eight; more decompositions exist.
