Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719146, here are decompositions:

5 + 8719141 = 8719146
13 + 8719133 = 8719146
19 + 8719127 = 8719146
47 + 8719099 = 8719146
89 + 8719057 = 8719146
97 + 8719049 = 8719146
109 + 8719037 = 8719146
173 + 8718973 = 8719146

Showing the first eight; more decompositions exist.
