Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66544, here are decompositions:

3 + 66541 = 66544
11 + 66533 = 66544
53 + 66491 = 66544
113 + 66431 = 66544
131 + 66413 = 66544
167 + 66377 = 66544
197 + 66347 = 66544
251 + 66293 = 66544

Showing the first eight; more decompositions exist.
