Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945810, here are decompositions:

11 + 945799 = 945810
23 + 945787 = 945810
43 + 945767 = 945810
71 + 945739 = 945810
79 + 945731 = 945810
109 + 945701 = 945810
137 + 945673 = 945810
139 + 945671 = 945810

Showing the first eight; more decompositions exist.
