Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66534, here are decompositions:

5 + 66529 = 66534
11 + 66523 = 66534
43 + 66491 = 66534
67 + 66467 = 66534
71 + 66463 = 66534
103 + 66431 = 66534
131 + 66403 = 66534
151 + 66383 = 66534

Showing the first eight; more decompositions exist.
