Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945812, here are decompositions:

3 + 945809 = 945812
13 + 945799 = 945812
73 + 945739 = 945812
79 + 945733 = 945812
139 + 945673 = 945812
181 + 945631 = 945812
211 + 945601 = 945812
223 + 945589 = 945812

Showing the first eight; more decompositions exist.
