Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020880, here are decompositions:

41 + 1020839 = 1020880
53 + 1020827 = 1020880
59 + 1020821 = 1020880
83 + 1020797 = 1020880
101 + 1020779 = 1020880
137 + 1020743 = 1020880
173 + 1020707 = 1020880
191 + 1020689 = 1020880

Showing the first eight; more decompositions exist.
