Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641684, here are decompositions:

11 + 8641673 = 8641684
41 + 8641643 = 8641684
53 + 8641631 = 8641684
71 + 8641613 = 8641684
113 + 8641571 = 8641684
137 + 8641547 = 8641684
167 + 8641517 = 8641684
251 + 8641433 = 8641684

Showing the first eight; more decompositions exist.
