Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548380, here are decompositions:

17 + 548363 = 548380
29 + 548351 = 548380
71 + 548309 = 548380
89 + 548291 = 548380
137 + 548243 = 548380
167 + 548213 = 548380
179 + 548201 = 548380
191 + 548189 = 548380

Showing the first eight; more decompositions exist.
