Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044820, here are decompositions:

11 + 1044809 = 1044820
41 + 1044779 = 1044820
53 + 1044767 = 1044820
59 + 1044761 = 1044820
71 + 1044749 = 1044820
83 + 1044737 = 1044820
131 + 1044689 = 1044820
167 + 1044653 = 1044820

Showing the first eight; more decompositions exist.
