Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645052, here are decompositions:

5 + 8645047 = 8645052
23 + 8645029 = 8645052
29 + 8645023 = 8645052
41 + 8645011 = 8645052
43 + 8645009 = 8645052
61 + 8644991 = 8645052
89 + 8644963 = 8645052
103 + 8644949 = 8645052

Showing the first eight; more decompositions exist.
