Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645802, here are decompositions:

13 + 8645789 = 8645802
29 + 8645773 = 8645802
41 + 8645761 = 8645802
43 + 8645759 = 8645802
73 + 8645729 = 8645802
83 + 8645719 = 8645802
149 + 8645653 = 8645802
223 + 8645579 = 8645802

Showing the first eight; more decompositions exist.
