Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641752, here are decompositions:

5 + 8641747 = 8641752
11 + 8641741 = 8641752
19 + 8641733 = 8641752
43 + 8641709 = 8641752
79 + 8641673 = 8641752
83 + 8641669 = 8641752
101 + 8641651 = 8641752
109 + 8641643 = 8641752

Showing the first eight; more decompositions exist.
