Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641624, here are decompositions:

3 + 8641621 = 8641624
11 + 8641613 = 8641624
53 + 8641571 = 8641624
83 + 8641541 = 8641624
107 + 8641517 = 8641624
191 + 8641433 = 8641624
263 + 8641361 = 8641624
293 + 8641331 = 8641624

Showing the first eight; more decompositions exist.
