Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000878, here are decompositions:

17 + 1000861 = 1000878
19 + 1000859 = 1000878
29 + 1000849 = 1000878
31 + 1000847 = 1000878
101 + 1000777 = 1000878
157 + 1000721 = 1000878
181 + 1000697 = 1000878
199 + 1000679 = 1000878

Showing the first eight; more decompositions exist.
