Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45680, here are decompositions:

3 + 45677 = 45680
7 + 45673 = 45680
13 + 45667 = 45680
67 + 45613 = 45680
127 + 45553 = 45680
139 + 45541 = 45680
157 + 45523 = 45680
199 + 45481 = 45680

Showing the first eight; more decompositions exist.
