Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65020, here are decompositions:

17 + 65003 = 65020
23 + 64997 = 65020
83 + 64937 = 65020
101 + 64919 = 65020
149 + 64871 = 65020
167 + 64853 = 65020
227 + 64793 = 65020
239 + 64781 = 65020

Showing the first eight; more decompositions exist.
