Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662690, here are decompositions:

41 + 8662649 = 8662690
107 + 8662583 = 8662690
137 + 8662553 = 8662690
149 + 8662541 = 8662690
173 + 8662517 = 8662690
293 + 8662397 = 8662690
347 + 8662343 = 8662690
353 + 8662337 = 8662690

Showing the first eight; more decompositions exist.
