Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724078, here are decompositions:

5 + 8724073 = 8724078
7 + 8724071 = 8724078
101 + 8723977 = 8724078
127 + 8723951 = 8724078
131 + 8723947 = 8724078
149 + 8723929 = 8724078
157 + 8723921 = 8724078
179 + 8723899 = 8724078

Showing the first eight; more decompositions exist.
