Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019398, here are decompositions:

41 + 1019357 = 1019398
47 + 1019351 = 1019398
59 + 1019339 = 1019398
101 + 1019297 = 1019398
131 + 1019267 = 1019398
137 + 1019261 = 1019398
269 + 1019129 = 1019398
431 + 1018967 = 1019398

Showing the first eight; more decompositions exist.
