Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675140, here are decompositions:

3 + 8675137 = 8675140
29 + 8675111 = 8675140
41 + 8675099 = 8675140
107 + 8675033 = 8675140
113 + 8675027 = 8675140
137 + 8675003 = 8675140
179 + 8674961 = 8675140
239 + 8674901 = 8675140

Showing the first eight; more decompositions exist.
