Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469690, here are decompositions:

3 + 469687 = 469690
17 + 469673 = 469690
41 + 469649 = 469690
59 + 469631 = 469690
101 + 469589 = 469690
107 + 469583 = 469690
149 + 469541 = 469690
233 + 469457 = 469690

Showing the first eight; more decompositions exist.
