Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45130, here are decompositions:

3 + 45127 = 45130
11 + 45119 = 45130
47 + 45083 = 45130
53 + 45077 = 45130
167 + 44963 = 45130
191 + 44939 = 45130
251 + 44879 = 45130
263 + 44867 = 45130

Showing the first eight; more decompositions exist.
