Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028492, here are decompositions:

13 + 1028479 = 1028492
19 + 1028473 = 1028492
103 + 1028389 = 1028492
163 + 1028329 = 1028492
229 + 1028263 = 1028492
271 + 1028221 = 1028492
379 + 1028113 = 1028492
463 + 1028029 = 1028492

Showing the first eight; more decompositions exist.
