Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538530, here are decompositions:

7 + 538523 = 538530
11 + 538519 = 538530
17 + 538513 = 538530
19 + 538511 = 538530
43 + 538487 = 538530
59 + 538471 = 538530
73 + 538457 = 538530
107 + 538423 = 538530

Showing the first eight; more decompositions exist.
