Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526816, here are decompositions:

53 + 526763 = 526816
83 + 526733 = 526816
107 + 526709 = 526816
113 + 526703 = 526816
137 + 526679 = 526816
149 + 526667 = 526816
167 + 526649 = 526816
179 + 526637 = 526816

Showing the first eight; more decompositions exist.
