Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465728, here are decompositions:

7 + 465721 = 465728
79 + 465649 = 465728
97 + 465631 = 465728
199 + 465529 = 465728
349 + 465379 = 465728
397 + 465331 = 465728
409 + 465319 = 465728
457 + 465271 = 465728

Showing the first eight; more decompositions exist.
