Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538988, here are decompositions:

61 + 538927 = 538988
67 + 538921 = 538988
199 + 538789 = 538988
211 + 538777 = 538988
277 + 538711 = 538988
337 + 538651 = 538988
367 + 538621 = 538988
409 + 538579 = 538988

Showing the first eight; more decompositions exist.
