Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720350, here are decompositions:

3 + 8720347 = 8720350
11 + 8720339 = 8720350
29 + 8720321 = 8720350
173 + 8720177 = 8720350
179 + 8720171 = 8720350
239 + 8720111 = 8720350
263 + 8720087 = 8720350
269 + 8720081 = 8720350

Showing the first eight; more decompositions exist.
