Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 535638, here are decompositions:

11 + 535627 = 535638
29 + 535609 = 535638
31 + 535607 = 535638
67 + 535571 = 535638
109 + 535529 = 535638
127 + 535511 = 535638
139 + 535499 = 535638
149 + 535489 = 535638

Showing the first eight; more decompositions exist.
