Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523812, here are decompositions:

11 + 523801 = 523812
19 + 523793 = 523812
41 + 523771 = 523812
53 + 523759 = 523812
71 + 523741 = 523812
83 + 523729 = 523812
131 + 523681 = 523812
139 + 523673 = 523812

Showing the first eight; more decompositions exist.
