Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671140, here are decompositions:

7 + 8671133 = 8671140
13 + 8671127 = 8671140
41 + 8671099 = 8671140
43 + 8671097 = 8671140
73 + 8671067 = 8671140
83 + 8671057 = 8671140
89 + 8671051 = 8671140
109 + 8671031 = 8671140

Showing the first eight; more decompositions exist.
