Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723372, here are decompositions:

13 + 8723359 = 8723372
19 + 8723353 = 8723372
61 + 8723311 = 8723372
181 + 8723191 = 8723372
223 + 8723149 = 8723372
283 + 8723089 = 8723372
331 + 8723041 = 8723372
373 + 8722999 = 8723372

Showing the first eight; more decompositions exist.
