Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678338, here are decompositions:

5 + 8678333 = 8678338
101 + 8678237 = 8678338
191 + 8678147 = 8678338
197 + 8678141 = 8678338
257 + 8678081 = 8678338
269 + 8678069 = 8678338
281 + 8678057 = 8678338
311 + 8678027 = 8678338

Showing the first eight; more decompositions exist.
