Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521634, here are decompositions:

31 + 521603 = 521634
53 + 521581 = 521634
67 + 521567 = 521634
83 + 521551 = 521634
97 + 521537 = 521634
101 + 521533 = 521634
107 + 521527 = 521634
131 + 521503 = 521634

Showing the first eight; more decompositions exist.
