Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687290, here are decompositions:

41 + 8687249 = 8687290
83 + 8687207 = 8687290
107 + 8687183 = 8687290
149 + 8687141 = 8687290
173 + 8687117 = 8687290
197 + 8687093 = 8687290
263 + 8687027 = 8687290
389 + 8686901 = 8687290

Showing the first eight; more decompositions exist.
