Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019388, here are decompositions:

11 + 1019377 = 1019388
31 + 1019357 = 1019388
37 + 1019351 = 1019388
59 + 1019329 = 1019388
107 + 1019281 = 1019388
127 + 1019261 = 1019388
131 + 1019257 = 1019388
137 + 1019251 = 1019388

Showing the first eight; more decompositions exist.
