Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469290, here are decompositions:

7 + 469283 = 469290
11 + 469279 = 469290
23 + 469267 = 469290
37 + 469253 = 469290
53 + 469237 = 469290
61 + 469229 = 469290
71 + 469219 = 469290
83 + 469207 = 469290

Showing the first eight; more decompositions exist.
