Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64518, here are decompositions:

5 + 64513 = 64518
19 + 64499 = 64518
29 + 64489 = 64518
67 + 64451 = 64518
79 + 64439 = 64518
137 + 64381 = 64518
191 + 64327 = 64518
199 + 64319 = 64518

Showing the first eight; more decompositions exist.
