Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045216, here are decompositions:

17 + 1045199 = 1045216
23 + 1045193 = 1045216
59 + 1045157 = 1045216
173 + 1045043 = 1045216
383 + 1044833 = 1045216
449 + 1044767 = 1045216
467 + 1044749 = 1045216
479 + 1044737 = 1045216

Showing the first eight; more decompositions exist.
