Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618404, here are decompositions:

17 + 8618387 = 8618404
107 + 8618297 = 8618404
131 + 8618273 = 8618404
167 + 8618237 = 8618404
191 + 8618213 = 8618404
257 + 8618147 = 8618404
317 + 8618087 = 8618404
383 + 8618021 = 8618404

Showing the first eight; more decompositions exist.
