Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526812, here are decompositions:

31 + 526781 = 526812
53 + 526759 = 526812
71 + 526741 = 526812
73 + 526739 = 526812
79 + 526733 = 526812
103 + 526709 = 526812
109 + 526703 = 526812
131 + 526681 = 526812

Showing the first eight; more decompositions exist.
