Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65220, here are decompositions:

7 + 65213 = 65220
17 + 65203 = 65220
37 + 65183 = 65220
41 + 65179 = 65220
47 + 65173 = 65220
53 + 65167 = 65220
73 + 65147 = 65220
79 + 65141 = 65220

Showing the first eight; more decompositions exist.
