Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1010878, here are decompositions:

17 + 1010861 = 1010878
107 + 1010771 = 1010878
131 + 1010747 = 1010878
191 + 1010687 = 1010878
251 + 1010627 = 1010878
311 + 1010567 = 1010878
359 + 1010519 = 1010878
467 + 1010411 = 1010878

Showing the first eight; more decompositions exist.
