Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724168, here are decompositions:

7 + 8724161 = 8724168
29 + 8724139 = 8724168
41 + 8724127 = 8724168
67 + 8724101 = 8724168
97 + 8724071 = 8724168
181 + 8723987 = 8724168
191 + 8723977 = 8724168
239 + 8723929 = 8724168

Showing the first eight; more decompositions exist.
