Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719170, here are decompositions:

7 + 8719163 = 8719170
11 + 8719159 = 8719170
29 + 8719141 = 8719170
37 + 8719133 = 8719170
43 + 8719127 = 8719170
71 + 8719099 = 8719170
113 + 8719057 = 8719170
139 + 8719031 = 8719170

Showing the first eight; more decompositions exist.
