Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000818, here are decompositions:

41 + 1000777 = 1000818
97 + 1000721 = 1000818
127 + 1000691 = 1000818
139 + 1000679 = 1000818
149 + 1000669 = 1000818
151 + 1000667 = 1000818
167 + 1000651 = 1000818
179 + 1000639 = 1000818

Showing the first eight; more decompositions exist.
