Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526800, here are decompositions:

19 + 526781 = 526800
23 + 526777 = 526800
37 + 526763 = 526800
41 + 526759 = 526800
59 + 526741 = 526800
61 + 526739 = 526800
67 + 526733 = 526800
83 + 526717 = 526800

Showing the first eight; more decompositions exist.
