Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000548, here are decompositions:

7 + 1000541 = 1000548
11 + 1000537 = 1000548
41 + 1000507 = 1000548
139 + 1000409 = 1000548
151 + 1000397 = 1000548
167 + 1000381 = 1000548
181 + 1000367 = 1000548
191 + 1000357 = 1000548

Showing the first eight; more decompositions exist.
