Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470620, here are decompositions:

11 + 470609 = 470620
23 + 470597 = 470620
41 + 470579 = 470620
89 + 470531 = 470620
107 + 470513 = 470620
131 + 470489 = 470620
149 + 470471 = 470620
167 + 470453 = 470620

Showing the first eight; more decompositions exist.
