Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465820, here are decompositions:

11 + 465809 = 465820
23 + 465797 = 465820
59 + 465761 = 465820
233 + 465587 = 465820
239 + 465581 = 465820
269 + 465551 = 465820
401 + 465419 = 465820
503 + 465317 = 465820

Showing the first eight; more decompositions exist.
