Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621752, here are decompositions:

3 + 8621749 = 8621752
5 + 8621747 = 8621752
59 + 8621693 = 8621752
71 + 8621681 = 8621752
443 + 8621309 = 8621752
509 + 8621243 = 8621752
563 + 8621189 = 8621752
569 + 8621183 = 8621752

Showing the first eight; more decompositions exist.
