Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721176, here are decompositions:

19 + 8721157 = 8721176
97 + 8721079 = 8721176
127 + 8721049 = 8721176
199 + 8720977 = 8721176
223 + 8720953 = 8721176
229 + 8720947 = 8721176
337 + 8720839 = 8721176
367 + 8720809 = 8721176

Showing the first eight; more decompositions exist.
