Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549988, here are decompositions:

11 + 549977 = 549988
149 + 549839 = 549988
239 + 549749 = 549988
251 + 549737 = 549988
269 + 549719 = 549988
281 + 549707 = 549988
347 + 549641 = 549988
401 + 549587 = 549988

Showing the first eight; more decompositions exist.
