Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019430, here are decompositions:

7 + 1019423 = 1019430
17 + 1019413 = 1019430
19 + 1019411 = 1019430
31 + 1019399 = 1019430
53 + 1019377 = 1019430
73 + 1019357 = 1019430
79 + 1019351 = 1019430
101 + 1019329 = 1019430

Showing the first eight; more decompositions exist.
