Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526820, here are decompositions:

43 + 526777 = 526820
61 + 526759 = 526820
79 + 526741 = 526820
103 + 526717 = 526820
139 + 526681 = 526820
163 + 526657 = 526820
193 + 526627 = 526820
277 + 526543 = 526820

Showing the first eight; more decompositions exist.
