Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538736, here are decompositions:

13 + 538723 = 538736
139 + 538597 = 538736
157 + 538579 = 538736
223 + 538513 = 538736
313 + 538423 = 538736
337 + 538399 = 538736
379 + 538357 = 538736
433 + 538303 = 538736

Showing the first eight; more decompositions exist.
