Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019342, here are decompositions:

3 + 1019339 = 1019342
13 + 1019329 = 1019342
61 + 1019281 = 1019342
223 + 1019119 = 1019342
271 + 1019071 = 1019342
283 + 1019059 = 1019342
349 + 1018993 = 1019342
439 + 1018903 = 1019342

Showing the first eight; more decompositions exist.
