Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724018, here are decompositions:

5 + 8724013 = 8724018
31 + 8723987 = 8724018
41 + 8723977 = 8724018
67 + 8723951 = 8724018
71 + 8723947 = 8724018
89 + 8723929 = 8724018
97 + 8723921 = 8724018
109 + 8723909 = 8724018

Showing the first eight; more decompositions exist.
