Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691804, here are decompositions:

5 + 8691799 = 8691804
41 + 8691763 = 8691804
53 + 8691751 = 8691804
71 + 8691733 = 8691804
73 + 8691731 = 8691804
131 + 8691673 = 8691804
137 + 8691667 = 8691804
151 + 8691653 = 8691804

Showing the first eight; more decompositions exist.
