Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66522, here are decompositions:

13 + 66509 = 66522
23 + 66499 = 66522
31 + 66491 = 66522
59 + 66463 = 66522
73 + 66449 = 66522
109 + 66413 = 66522
139 + 66383 = 66522
149 + 66373 = 66522

Showing the first eight; more decompositions exist.
