Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646984, here are decompositions:

13 + 8646971 = 8646984
23 + 8646961 = 8646984
37 + 8646947 = 8646984
41 + 8646943 = 8646984
131 + 8646853 = 8646984
163 + 8646821 = 8646984
167 + 8646817 = 8646984
191 + 8646793 = 8646984

Showing the first eight; more decompositions exist.
