Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66526, here are decompositions:

3 + 66523 = 66526
17 + 66509 = 66526
59 + 66467 = 66526
113 + 66413 = 66526
149 + 66377 = 66526
167 + 66359 = 66526
179 + 66347 = 66526
233 + 66293 = 66526

Showing the first eight; more decompositions exist.
