Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618488, here are decompositions:

5 + 8618483 = 8618488
59 + 8618429 = 8618488
101 + 8618387 = 8618488
149 + 8618339 = 8618488
191 + 8618297 = 8618488
251 + 8618237 = 8618488
401 + 8618087 = 8618488
467 + 8618021 = 8618488

Showing the first eight; more decompositions exist.
