Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028372, here are decompositions:

43 + 1028329 = 1028372
109 + 1028263 = 1028372
151 + 1028221 = 1028372
181 + 1028191 = 1028372
223 + 1028149 = 1028372
271 + 1028101 = 1028372
283 + 1028089 = 1028372
349 + 1028023 = 1028372

Showing the first eight; more decompositions exist.
