Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700372, here are decompositions:

11 + 8700361 = 8700372
19 + 8700353 = 8700372
73 + 8700299 = 8700372
89 + 8700283 = 8700372
179 + 8700193 = 8700372
211 + 8700161 = 8700372
251 + 8700121 = 8700372
293 + 8700079 = 8700372

Showing the first eight; more decompositions exist.
