Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538584, here are decompositions:

5 + 538579 = 538584
17 + 538567 = 538584
23 + 538561 = 538584
31 + 538553 = 538584
61 + 538523 = 538584
71 + 538513 = 538584
73 + 538511 = 538584
97 + 538487 = 538584

Showing the first eight; more decompositions exist.
