Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708290, here are decompositions:

29 + 8708261 = 8708290
89 + 8708201 = 8708290
131 + 8708159 = 8708290
137 + 8708153 = 8708290
197 + 8708093 = 8708290
251 + 8708039 = 8708290
293 + 8707997 = 8708290
449 + 8707841 = 8708290

Showing the first eight; more decompositions exist.
