Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009372, here are decompositions:

3 + 1009369 = 1009372
11 + 1009361 = 1009372
29 + 1009343 = 1009372
53 + 1009319 = 1009372
71 + 1009301 = 1009372
83 + 1009289 = 1009372
113 + 1009259 = 1009372
173 + 1009199 = 1009372

Showing the first eight; more decompositions exist.
