Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045618, here are decompositions:

11 + 1045607 = 1045618
47 + 1045571 = 1045618
59 + 1045559 = 1045618
71 + 1045547 = 1045618
89 + 1045529 = 1045618
131 + 1045487 = 1045618
149 + 1045469 = 1045618
191 + 1045427 = 1045618

Showing the first eight; more decompositions exist.
