Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031328, here are decompositions:

5 + 1031323 = 1031328
19 + 1031309 = 1031328
29 + 1031299 = 1031328
37 + 1031291 = 1031328
47 + 1031281 = 1031328
61 + 1031267 = 1031328
97 + 1031231 = 1031328
139 + 1031189 = 1031328

Showing the first eight; more decompositions exist.
