Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678418, here are decompositions:

19 + 8678399 = 8678418
59 + 8678359 = 8678418
79 + 8678339 = 8678418
107 + 8678311 = 8678418
181 + 8678237 = 8678418
239 + 8678179 = 8678418
257 + 8678161 = 8678418
269 + 8678149 = 8678418

Showing the first eight; more decompositions exist.
