Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662438, here are decompositions:

41 + 8662397 = 8662438
89 + 8662349 = 8662438
101 + 8662337 = 8662438
179 + 8662259 = 8662438
251 + 8662187 = 8662438
269 + 8662169 = 8662438
311 + 8662127 = 8662438
347 + 8662091 = 8662438

Showing the first eight; more decompositions exist.
