Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641884, here are decompositions:

11 + 8641873 = 8641884
67 + 8641817 = 8641884
101 + 8641783 = 8641884
103 + 8641781 = 8641884
137 + 8641747 = 8641884
151 + 8641733 = 8641884
211 + 8641673 = 8641884
233 + 8641651 = 8641884

Showing the first eight; more decompositions exist.
