Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45732, here are decompositions:

41 + 45691 = 45732
59 + 45673 = 45732
73 + 45659 = 45732
101 + 45631 = 45732
163 + 45569 = 45732
179 + 45553 = 45732
191 + 45541 = 45732
199 + 45533 = 45732

Showing the first eight; more decompositions exist.
