Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045668, here are decompositions:

5 + 1045663 = 1045668
17 + 1045651 = 1045668
47 + 1045621 = 1045668
61 + 1045607 = 1045668
97 + 1045571 = 1045668
109 + 1045559 = 1045668
139 + 1045529 = 1045668
181 + 1045487 = 1045668

Showing the first eight; more decompositions exist.
