Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012864, here are decompositions:

3 + 1012861 = 1012864
53 + 1012811 = 1012864
101 + 1012763 = 1012864
113 + 1012751 = 1012864
131 + 1012733 = 1012864
173 + 1012691 = 1012864
227 + 1012637 = 1012864
233 + 1012631 = 1012864

Showing the first eight; more decompositions exist.
