Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469530, here are decompositions:

29 + 469501 = 469530
43 + 469487 = 469530
73 + 469457 = 469530
101 + 469429 = 469530
151 + 469379 = 469530
163 + 469367 = 469530
167 + 469363 = 469530
179 + 469351 = 469530

Showing the first eight; more decompositions exist.
