Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538550, here are decompositions:

31 + 538519 = 538550
37 + 538513 = 538550
79 + 538471 = 538550
127 + 538423 = 538550
139 + 538411 = 538550
151 + 538399 = 538550
193 + 538357 = 538550
241 + 538309 = 538550

Showing the first eight; more decompositions exist.
