Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470428, here are decompositions:

11 + 470417 = 470428
17 + 470411 = 470428
29 + 470399 = 470428
131 + 470297 = 470428
149 + 470279 = 470428
227 + 470201 = 470428
347 + 470081 = 470428
389 + 470039 = 470428

Showing the first eight; more decompositions exist.
