Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012840, here are decompositions:

11 + 1012829 = 1012840
29 + 1012811 = 1012840
71 + 1012769 = 1012840
89 + 1012751 = 1012840
107 + 1012733 = 1012840
137 + 1012703 = 1012840
149 + 1012691 = 1012840
239 + 1012601 = 1012840

Showing the first eight; more decompositions exist.
