Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030628, here are decompositions:

199 + 1030429 = 1030628
211 + 1030417 = 1030628
271 + 1030357 = 1030628
331 + 1030297 = 1030628
337 + 1030291 = 1030628
409 + 1030219 = 1030628
601 + 1030027 = 1030628
607 + 1030021 = 1030628

Showing the first eight; more decompositions exist.
