Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545772, here are decompositions:

13 + 545759 = 545772
23 + 545749 = 545772
41 + 545731 = 545772
61 + 545711 = 545772
109 + 545663 = 545772
131 + 545641 = 545772
151 + 545621 = 545772
163 + 545609 = 545772

Showing the first eight; more decompositions exist.
