Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642904, here are decompositions:

7 + 8642897 = 8642904
41 + 8642863 = 8642904
43 + 8642861 = 8642904
47 + 8642857 = 8642904
131 + 8642773 = 8642904
157 + 8642747 = 8642904
181 + 8642723 = 8642904
271 + 8642633 = 8642904

Showing the first eight; more decompositions exist.
