Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724082, here are decompositions:

11 + 8724071 = 8724082
89 + 8723993 = 8724082
131 + 8723951 = 8724082
149 + 8723933 = 8724082
173 + 8723909 = 8724082
179 + 8723903 = 8724082
293 + 8723789 = 8724082
443 + 8723639 = 8724082

Showing the first eight; more decompositions exist.
