Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66450, here are decompositions:

19 + 66431 = 66450
37 + 66413 = 66450
47 + 66403 = 66450
67 + 66383 = 66450
73 + 66377 = 66450
89 + 66361 = 66450
103 + 66347 = 66450
107 + 66343 = 66450

Showing the first eight; more decompositions exist.
