Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724120, here are decompositions:

19 + 8724101 = 8724120
47 + 8724073 = 8724120
107 + 8724013 = 8724120
127 + 8723993 = 8724120
173 + 8723947 = 8724120
191 + 8723929 = 8724120
199 + 8723921 = 8724120
211 + 8723909 = 8724120

Showing the first eight; more decompositions exist.
