Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66442, here are decompositions:

11 + 66431 = 66442
29 + 66413 = 66442
59 + 66383 = 66442
83 + 66359 = 66442
149 + 66293 = 66442
251 + 66191 = 66442
263 + 66179 = 66442
269 + 66173 = 66442

Showing the first eight; more decompositions exist.
