Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720030, here are decompositions:

3 + 8720027 = 8720030
31 + 8719999 = 8720030
43 + 8719987 = 8720030
79 + 8719951 = 8720030
127 + 8719903 = 8720030
157 + 8719873 = 8720030
199 + 8719831 = 8720030
211 + 8719819 = 8720030

Showing the first eight; more decompositions exist.
