Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66430, here are decompositions:

17 + 66413 = 66430
47 + 66383 = 66430
53 + 66377 = 66430
71 + 66359 = 66430
83 + 66347 = 66430
137 + 66293 = 66430
191 + 66239 = 66430
239 + 66191 = 66430

Showing the first eight; more decompositions exist.
