Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526806, here are decompositions:

29 + 526777 = 526806
43 + 526763 = 526806
47 + 526759 = 526806
67 + 526739 = 526806
73 + 526733 = 526806
89 + 526717 = 526806
97 + 526709 = 526806
103 + 526703 = 526806

Showing the first eight; more decompositions exist.
