Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931812, here are decompositions:

23 + 931789 = 931812
29 + 931783 = 931812
31 + 931781 = 931812
61 + 931751 = 931812
73 + 931739 = 931812
83 + 931729 = 931812
103 + 931709 = 931812
173 + 931639 = 931812

Showing the first eight; more decompositions exist.
