Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532638, here are decompositions:

5 + 532633 = 532638
17 + 532621 = 532638
19 + 532619 = 532638
31 + 532607 = 532638
37 + 532601 = 532638
101 + 532537 = 532638
107 + 532531 = 532638
109 + 532529 = 532638

Showing the first eight; more decompositions exist.
