Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65780, here are decompositions:

3 + 65777 = 65780
19 + 65761 = 65780
61 + 65719 = 65780
67 + 65713 = 65780
73 + 65707 = 65780
79 + 65701 = 65780
103 + 65677 = 65780
151 + 65629 = 65780

Showing the first eight; more decompositions exist.
