Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028860, here are decompositions:

17 + 1028843 = 1028860
23 + 1028837 = 1028860
83 + 1028777 = 1028860
113 + 1028747 = 1028860
179 + 1028681 = 1028860
191 + 1028669 = 1028860
197 + 1028663 = 1028860
263 + 1028597 = 1028860

Showing the first eight; more decompositions exist.
