Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526786, here are decompositions:

5 + 526781 = 526786
23 + 526763 = 526786
47 + 526739 = 526786
53 + 526733 = 526786
83 + 526703 = 526786
107 + 526679 = 526786
137 + 526649 = 526786
149 + 526637 = 526786

Showing the first eight; more decompositions exist.
