Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719188, here are decompositions:

11 + 8719177 = 8719188
29 + 8719159 = 8719188
47 + 8719141 = 8719188
61 + 8719127 = 8719188
89 + 8719099 = 8719188
131 + 8719057 = 8719188
139 + 8719049 = 8719188
151 + 8719037 = 8719188

Showing the first eight; more decompositions exist.
