Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736140, here are decompositions:

13 + 8736127 = 8736140
31 + 8736109 = 8736140
43 + 8736097 = 8736140
67 + 8736073 = 8736140
79 + 8736061 = 8736140
103 + 8736037 = 8736140
139 + 8736001 = 8736140
199 + 8735941 = 8736140

Showing the first eight; more decompositions exist.
