Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526490, here are decompositions:

7 + 526483 = 526490
31 + 526459 = 526490
37 + 526453 = 526490
61 + 526429 = 526490
67 + 526423 = 526490
103 + 526387 = 526490
109 + 526381 = 526490
193 + 526297 = 526490

Showing the first eight; more decompositions exist.
