Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678140, here are decompositions:

11 + 8678129 = 8678140
47 + 8678093 = 8678140
59 + 8678081 = 8678140
71 + 8678069 = 8678140
83 + 8678057 = 8678140
89 + 8678051 = 8678140
101 + 8678039 = 8678140
113 + 8678027 = 8678140

Showing the first eight; more decompositions exist.
