Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468728, here are decompositions:

19 + 468709 = 468728
31 + 468697 = 468728
37 + 468691 = 468728
61 + 468667 = 468728
67 + 468661 = 468728
109 + 468619 = 468728
151 + 468577 = 468728
229 + 468499 = 468728

Showing the first eight; more decompositions exist.
