Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045512, here are decompositions:

5 + 1045507 = 1045512
19 + 1045493 = 1045512
43 + 1045469 = 1045512
89 + 1045423 = 1045512
101 + 1045411 = 1045512
103 + 1045409 = 1045512
163 + 1045349 = 1045512
191 + 1045321 = 1045512

Showing the first eight; more decompositions exist.
