Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009390, here are decompositions:

3 + 1009387 = 1009390
17 + 1009373 = 1009390
29 + 1009361 = 1009390
47 + 1009343 = 1009390
71 + 1009319 = 1009390
89 + 1009301 = 1009390
101 + 1009289 = 1009390
131 + 1009259 = 1009390

Showing the first eight; more decompositions exist.
