Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028392, here are decompositions:

3 + 1028389 = 1028392
59 + 1028333 = 1028392
83 + 1028309 = 1028392
89 + 1028303 = 1028392
149 + 1028243 = 1028392
179 + 1028213 = 1028392
191 + 1028201 = 1028392
251 + 1028141 = 1028392

Showing the first eight; more decompositions exist.
