Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45290, here are decompositions:

31 + 45259 = 45290
43 + 45247 = 45290
109 + 45181 = 45290
151 + 45139 = 45290
163 + 45127 = 45290
229 + 45061 = 45290
277 + 45013 = 45290
283 + 45007 = 45290

Showing the first eight; more decompositions exist.
