Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 462820, here are decompositions:

47 + 462773 = 462820
101 + 462719 = 462820
107 + 462713 = 462820
167 + 462653 = 462820
179 + 462641 = 462820
191 + 462629 = 462820
251 + 462569 = 462820
263 + 462557 = 462820

Showing the first eight; more decompositions exist.
