Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45280, here are decompositions:

17 + 45263 = 45280
47 + 45233 = 45280
83 + 45197 = 45280
89 + 45191 = 45280
101 + 45179 = 45280
149 + 45131 = 45280
197 + 45083 = 45280
227 + 45053 = 45280

Showing the first eight; more decompositions exist.
