Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45740, here are decompositions:

3 + 45737 = 45740
43 + 45697 = 45740
67 + 45673 = 45740
73 + 45667 = 45740
109 + 45631 = 45740
127 + 45613 = 45740
151 + 45589 = 45740
199 + 45541 = 45740

Showing the first eight; more decompositions exist.
