Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645058, here are decompositions:

5 + 8645053 = 8645058
11 + 8645047 = 8645058
29 + 8645029 = 8645058
47 + 8645011 = 8645058
67 + 8644991 = 8645058
101 + 8644957 = 8645058
109 + 8644949 = 8645058
131 + 8644927 = 8645058

Showing the first eight; more decompositions exist.
