Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028394, here are decompositions:

5 + 1028389 = 1028394
61 + 1028333 = 1028394
67 + 1028327 = 1028394
131 + 1028263 = 1028394
151 + 1028243 = 1028394
163 + 1028231 = 1028394
173 + 1028221 = 1028394
181 + 1028213 = 1028394

Showing the first eight; more decompositions exist.
