Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465780, here are decompositions:

19 + 465761 = 465780
37 + 465743 = 465780
41 + 465739 = 465780
59 + 465721 = 465780
79 + 465701 = 465780
101 + 465679 = 465780
131 + 465649 = 465780
137 + 465643 = 465780

Showing the first eight; more decompositions exist.
