Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722372, here are decompositions:

5 + 8722367 = 8722372
11 + 8722361 = 8722372
41 + 8722331 = 8722372
89 + 8722283 = 8722372
149 + 8722223 = 8722372
179 + 8722193 = 8722372
293 + 8722079 = 8722372
353 + 8722019 = 8722372

Showing the first eight; more decompositions exist.
