Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45816, here are decompositions:

37 + 45779 = 45816
53 + 45763 = 45816
59 + 45757 = 45816
79 + 45737 = 45816
109 + 45707 = 45816
139 + 45677 = 45816
149 + 45667 = 45816
157 + 45659 = 45816

Showing the first eight; more decompositions exist.
