Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690146, here are decompositions:

29 + 8690117 = 8690146
53 + 8690093 = 8690146
83 + 8690063 = 8690146
149 + 8689997 = 8690146
167 + 8689979 = 8690146
197 + 8689949 = 8690146
293 + 8689853 = 8690146
347 + 8689799 = 8690146

Showing the first eight; more decompositions exist.
