Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000828, here are decompositions:

107 + 1000721 = 1000828
131 + 1000697 = 1000828
137 + 1000691 = 1000828
149 + 1000679 = 1000828
239 + 1000589 = 1000828
251 + 1000577 = 1000828
281 + 1000547 = 1000828
401 + 1000427 = 1000828

Showing the first eight; more decompositions exist.
