Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019380, here are decompositions:

3 + 1019377 = 1019380
23 + 1019357 = 1019380
29 + 1019351 = 1019380
41 + 1019339 = 1019380
83 + 1019297 = 1019380
107 + 1019273 = 1019380
113 + 1019267 = 1019380
251 + 1019129 = 1019380

Showing the first eight; more decompositions exist.
