Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469428, here are decompositions:

17 + 469411 = 469428
31 + 469397 = 469428
59 + 469369 = 469428
61 + 469367 = 469428
97 + 469331 = 469428
107 + 469321 = 469428
149 + 469279 = 469428
191 + 469237 = 469428

Showing the first eight; more decompositions exist.
