Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469790, here are decompositions:

3 + 469787 = 469790
37 + 469753 = 469790
43 + 469747 = 469790
67 + 469723 = 469790
73 + 469717 = 469790
103 + 469687 = 469790
163 + 469627 = 469790
229 + 469561 = 469790

Showing the first eight; more decompositions exist.
