Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470858, here are decompositions:

67 + 470791 = 470858
79 + 470779 = 470858
109 + 470749 = 470858
127 + 470731 = 470858
139 + 470719 = 470858
211 + 470647 = 470858
307 + 470551 = 470858
337 + 470521 = 470858

Showing the first eight; more decompositions exist.
