Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009378, here are decompositions:

5 + 1009373 = 1009378
17 + 1009361 = 1009378
59 + 1009319 = 1009378
89 + 1009289 = 1009378
131 + 1009247 = 1009378
179 + 1009199 = 1009378
239 + 1009139 = 1009378
257 + 1009121 = 1009378

Showing the first eight; more decompositions exist.
