Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465680, here are decompositions:

31 + 465649 = 465680
37 + 465643 = 465680
139 + 465541 = 465680
151 + 465529 = 465680
157 + 465523 = 465680
211 + 465469 = 465680
307 + 465373 = 465680
349 + 465331 = 465680

Showing the first eight; more decompositions exist.
