Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719158, here are decompositions:

17 + 8719141 = 8719158
31 + 8719127 = 8719158
59 + 8719099 = 8719158
101 + 8719057 = 8719158
109 + 8719049 = 8719158
127 + 8719031 = 8719158
137 + 8719021 = 8719158
241 + 8718917 = 8719158

Showing the first eight; more decompositions exist.
