Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019402, here are decompositions:

3 + 1019399 = 1019402
73 + 1019329 = 1019402
151 + 1019251 = 1019402
193 + 1019209 = 1019402
229 + 1019173 = 1019402
283 + 1019119 = 1019402
331 + 1019071 = 1019402
379 + 1019023 = 1019402

Showing the first eight; more decompositions exist.
