Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629638, here are decompositions:

41 + 8629597 = 8629638
131 + 8629507 = 8629638
191 + 8629447 = 8629638
197 + 8629441 = 8629638
229 + 8629409 = 8629638
359 + 8629279 = 8629638
397 + 8629241 = 8629638
439 + 8629199 = 8629638

Showing the first eight; more decompositions exist.
