Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678128, here are decompositions:

47 + 8678081 = 8678128
59 + 8678069 = 8678128
71 + 8678057 = 8678128
89 + 8678039 = 8678128
101 + 8678027 = 8678128
149 + 8677979 = 8678128
167 + 8677961 = 8678128
281 + 8677847 = 8678128

Showing the first eight; more decompositions exist.
