Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66514, here are decompositions:

5 + 66509 = 66514
23 + 66491 = 66514
47 + 66467 = 66514
83 + 66431 = 66514
101 + 66413 = 66514
131 + 66383 = 66514
137 + 66377 = 66514
167 + 66347 = 66514

Showing the first eight; more decompositions exist.
