Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465872, here are decompositions:

31 + 465841 = 465872
73 + 465799 = 465872
151 + 465721 = 465872
193 + 465679 = 465872
223 + 465649 = 465872
229 + 465643 = 465872
241 + 465631 = 465872
331 + 465541 = 465872

Showing the first eight; more decompositions exist.
