Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538536, here are decompositions:

7 + 538529 = 538536
13 + 538523 = 538536
17 + 538519 = 538536
23 + 538513 = 538536
79 + 538457 = 538536
113 + 538423 = 538536
137 + 538399 = 538536
139 + 538397 = 538536

Showing the first eight; more decompositions exist.
