Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718140, here are decompositions:

31 + 8718109 = 8718140
37 + 8718103 = 8718140
43 + 8718097 = 8718140
97 + 8718043 = 8718140
127 + 8718013 = 8718140
181 + 8717959 = 8718140
271 + 8717869 = 8718140
283 + 8717857 = 8718140

Showing the first eight; more decompositions exist.
