Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45770, here are decompositions:

3 + 45767 = 45770
7 + 45763 = 45770
13 + 45757 = 45770
19 + 45751 = 45770
73 + 45697 = 45770
79 + 45691 = 45770
97 + 45673 = 45770
103 + 45667 = 45770

Showing the first eight; more decompositions exist.
