Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678908, here are decompositions:

5 + 8678903 = 8678908
131 + 8678777 = 8678908
149 + 8678759 = 8678908
167 + 8678741 = 8678908
239 + 8678669 = 8678908
269 + 8678639 = 8678908
389 + 8678519 = 8678908
401 + 8678507 = 8678908

Showing the first eight; more decompositions exist.
