Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105548, here are decompositions:

7 + 105541 = 105548
19 + 105529 = 105548
31 + 105517 = 105548
151 + 105397 = 105548
181 + 105367 = 105548
211 + 105337 = 105548
229 + 105319 = 105548
271 + 105277 = 105548

Showing the first eight; more decompositions exist.
