Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678404, here are decompositions:

5 + 8678399 = 8678404
11 + 8678393 = 8678404
41 + 8678363 = 8678404
71 + 8678333 = 8678404
167 + 8678237 = 8678404
191 + 8678213 = 8678404
257 + 8678147 = 8678404
263 + 8678141 = 8678404

Showing the first eight; more decompositions exist.
