Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526640, here are decompositions:

3 + 526637 = 526640
7 + 526633 = 526640
13 + 526627 = 526640
67 + 526573 = 526640
97 + 526543 = 526640
109 + 526531 = 526640
139 + 526501 = 526640
157 + 526483 = 526640

Showing the first eight; more decompositions exist.
