Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045828, here are decompositions:

29 + 1045799 = 1045828
89 + 1045739 = 1045828
101 + 1045727 = 1045828
137 + 1045691 = 1045828
149 + 1045679 = 1045828
257 + 1045571 = 1045828
269 + 1045559 = 1045828
281 + 1045547 = 1045828

Showing the first eight; more decompositions exist.
