Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720344, here are decompositions:

5 + 8720339 = 8720344
23 + 8720321 = 8720344
167 + 8720177 = 8720344
173 + 8720171 = 8720344
233 + 8720111 = 8720344
257 + 8720087 = 8720344
263 + 8720081 = 8720344
317 + 8720027 = 8720344

Showing the first eight; more decompositions exist.
