Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526638, here are decompositions:

5 + 526633 = 526638
11 + 526627 = 526638
19 + 526619 = 526638
37 + 526601 = 526638
67 + 526571 = 526638
107 + 526531 = 526638
127 + 526511 = 526638
137 + 526501 = 526638

Showing the first eight; more decompositions exist.
