Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045540, here are decompositions:

11 + 1045529 = 1045540
17 + 1045523 = 1045540
47 + 1045493 = 1045540
53 + 1045487 = 1045540
71 + 1045469 = 1045540
113 + 1045427 = 1045540
131 + 1045409 = 1045540
149 + 1045391 = 1045540

Showing the first eight; more decompositions exist.
