Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012942, here are decompositions:

11 + 1012931 = 1012942
23 + 1012919 = 1012942
113 + 1012829 = 1012942
131 + 1012811 = 1012942
173 + 1012769 = 1012942
179 + 1012763 = 1012942
191 + 1012751 = 1012942
239 + 1012703 = 1012942

Showing the first eight; more decompositions exist.
