Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526808, here are decompositions:

31 + 526777 = 526808
67 + 526741 = 526808
127 + 526681 = 526808
151 + 526657 = 526808
157 + 526651 = 526808
181 + 526627 = 526808
277 + 526531 = 526808
307 + 526501 = 526808

Showing the first eight; more decompositions exist.
