Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736040, here are decompositions:

3 + 8736037 = 8736040
107 + 8735933 = 8736040
149 + 8735891 = 8736040
179 + 8735861 = 8736040
191 + 8735849 = 8736040
227 + 8735813 = 8736040
251 + 8735789 = 8736040
263 + 8735777 = 8736040

Showing the first eight; more decompositions exist.
