Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531634, here are decompositions:

3 + 531631 = 531634
11 + 531623 = 531634
23 + 531611 = 531634
53 + 531581 = 531634
83 + 531551 = 531634
113 + 531521 = 531634
137 + 531497 = 531634
251 + 531383 = 531634

Showing the first eight; more decompositions exist.
