Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678556, here are decompositions:

37 + 8678519 = 8678556
83 + 8678473 = 8678556
109 + 8678447 = 8678556
157 + 8678399 = 8678556
163 + 8678393 = 8678556
193 + 8678363 = 8678556
197 + 8678359 = 8678556
223 + 8678333 = 8678556

Showing the first eight; more decompositions exist.
