Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009212, here are decompositions:

5 + 1009207 = 1009212
11 + 1009201 = 1009212
13 + 1009199 = 1009212
19 + 1009193 = 1009212
23 + 1009189 = 1009212
53 + 1009159 = 1009212
59 + 1009153 = 1009212
73 + 1009139 = 1009212

Showing the first eight; more decompositions exist.
