Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051828, here are decompositions:

17 + 1051811 = 1051828
47 + 1051781 = 1051828
131 + 1051697 = 1051828
179 + 1051649 = 1051828
227 + 1051601 = 1051828
257 + 1051571 = 1051828
269 + 1051559 = 1051828
347 + 1051481 = 1051828

Showing the first eight; more decompositions exist.
