Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012920, here are decompositions:

17 + 1012903 = 1012920
59 + 1012861 = 1012920
89 + 1012831 = 1012920
109 + 1012811 = 1012920
131 + 1012789 = 1012920
149 + 1012771 = 1012920
151 + 1012769 = 1012920
157 + 1012763 = 1012920

Showing the first eight; more decompositions exist.
