Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719166, here are decompositions:

3 + 8719163 = 8719166
7 + 8719159 = 8719166
67 + 8719099 = 8719166
109 + 8719057 = 8719166
163 + 8719003 = 8719166
193 + 8718973 = 8719166
307 + 8718859 = 8719166
367 + 8718799 = 8719166

Showing the first eight; more decompositions exist.
