Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746818, here are decompositions:

5 + 8746813 = 8746818
7 + 8746811 = 8746818
11 + 8746807 = 8746818
19 + 8746799 = 8746818
61 + 8746757 = 8746818
109 + 8746709 = 8746818
139 + 8746679 = 8746818
167 + 8746651 = 8746818

Showing the first eight; more decompositions exist.
