Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691944, here are decompositions:

3 + 8691941 = 8691944
7 + 8691937 = 8691944
43 + 8691901 = 8691944
61 + 8691883 = 8691944
181 + 8691763 = 8691944
193 + 8691751 = 8691944
211 + 8691733 = 8691944
271 + 8691673 = 8691944

Showing the first eight; more decompositions exist.
