Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641916, here are decompositions:

7 + 8641909 = 8641916
43 + 8641873 = 8641916
97 + 8641819 = 8641916
109 + 8641807 = 8641916
313 + 8641603 = 8641916
373 + 8641543 = 8641916
397 + 8641519 = 8641916
463 + 8641453 = 8641916

Showing the first eight; more decompositions exist.
