Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641698, here are decompositions:

29 + 8641669 = 8641698
47 + 8641651 = 8641698
67 + 8641631 = 8641698
127 + 8641571 = 8641698
151 + 8641547 = 8641698
157 + 8641541 = 8641698
179 + 8641519 = 8641698
181 + 8641517 = 8641698

Showing the first eight; more decompositions exist.
