Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012860, here are decompositions:

29 + 1012831 = 1012860
31 + 1012829 = 1012860
71 + 1012789 = 1012860
89 + 1012771 = 1012860
97 + 1012763 = 1012860
109 + 1012751 = 1012860
127 + 1012733 = 1012860
139 + 1012721 = 1012860

Showing the first eight; more decompositions exist.
