Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020392, here are decompositions:

3 + 1020389 = 1020392
13 + 1020379 = 1020392
31 + 1020361 = 1020392
229 + 1020163 = 1020392
283 + 1020109 = 1020392
313 + 1020079 = 1020392
349 + 1020043 = 1020392
379 + 1020013 = 1020392

Showing the first eight; more decompositions exist.
