Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45078, here are decompositions:

17 + 45061 = 45078
71 + 45007 = 45078
107 + 44971 = 45078
139 + 44939 = 45078
151 + 44927 = 45078
191 + 44887 = 45078
199 + 44879 = 45078
211 + 44867 = 45078

Showing the first eight; more decompositions exist.
