Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66390, here are decompositions:

7 + 66383 = 66390
13 + 66377 = 66390
17 + 66373 = 66390
29 + 66361 = 66390
31 + 66359 = 66390
43 + 66347 = 66390
47 + 66343 = 66390
53 + 66337 = 66390

Showing the first eight; more decompositions exist.
