Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45778, here are decompositions:

11 + 45767 = 45778
41 + 45737 = 45778
71 + 45707 = 45778
101 + 45677 = 45778
137 + 45641 = 45778
179 + 45599 = 45778
191 + 45587 = 45778
281 + 45497 = 45778

Showing the first eight; more decompositions exist.
