Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641554, here are decompositions:

7 + 8641547 = 8641554
11 + 8641543 = 8641554
13 + 8641541 = 8641554
37 + 8641517 = 8641554
41 + 8641513 = 8641554
83 + 8641471 = 8641554
101 + 8641453 = 8641554
193 + 8641361 = 8641554

Showing the first eight; more decompositions exist.
