Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66554, here are decompositions:

13 + 66541 = 66554
31 + 66523 = 66554
97 + 66457 = 66554
151 + 66403 = 66554
181 + 66373 = 66554
193 + 66361 = 66554
211 + 66343 = 66554
283 + 66271 = 66554

Showing the first eight; more decompositions exist.
