Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736072, here are decompositions:

11 + 8736061 = 8736072
13 + 8736059 = 8736072
31 + 8736041 = 8736072
71 + 8736001 = 8736072
101 + 8735971 = 8736072
131 + 8735941 = 8736072
139 + 8735933 = 8736072
181 + 8735891 = 8736072

Showing the first eight; more decompositions exist.
