Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720112, here are decompositions:

31 + 8720081 = 8720112
41 + 8720071 = 8720112
113 + 8719999 = 8720112
151 + 8719961 = 8720112
173 + 8719939 = 8720112
239 + 8719873 = 8720112
281 + 8719831 = 8720112
293 + 8719819 = 8720112

Showing the first eight; more decompositions exist.
