Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009380, here are decompositions:

7 + 1009373 = 1009380
11 + 1009369 = 1009380
19 + 1009361 = 1009380
23 + 1009357 = 1009380
37 + 1009343 = 1009380
59 + 1009321 = 1009380
61 + 1009319 = 1009380
79 + 1009301 = 1009380

Showing the first eight; more decompositions exist.
