Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470538, here are decompositions:

7 + 470531 = 470538
17 + 470521 = 470538
37 + 470501 = 470538
67 + 470471 = 470538
109 + 470429 = 470538
127 + 470411 = 470538
139 + 470399 = 470538
149 + 470389 = 470538

Showing the first eight; more decompositions exist.
