Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526818, here are decompositions:

37 + 526781 = 526818
41 + 526777 = 526818
59 + 526759 = 526818
79 + 526739 = 526818
101 + 526717 = 526818
109 + 526709 = 526818
137 + 526681 = 526818
139 + 526679 = 526818

Showing the first eight; more decompositions exist.
