Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549718, here are decompositions:

5 + 549713 = 549718
11 + 549707 = 549718
17 + 549701 = 549718
131 + 549587 = 549718
149 + 549569 = 549718
167 + 549551 = 549718
269 + 549449 = 549718
461 + 549257 = 549718

Showing the first eight; more decompositions exist.
