Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707208, here are decompositions:

19 + 8707189 = 8707208
61 + 8707147 = 8707208
151 + 8707057 = 8707208
229 + 8706979 = 8707208
241 + 8706967 = 8707208
271 + 8706937 = 8707208
337 + 8706871 = 8707208
379 + 8706829 = 8707208

Showing the first eight; more decompositions exist.
