Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720368, here are decompositions:

29 + 8720339 = 8720368
47 + 8720321 = 8720368
179 + 8720189 = 8720368
191 + 8720177 = 8720368
197 + 8720171 = 8720368
257 + 8720111 = 8720368
281 + 8720087 = 8720368
311 + 8720057 = 8720368

Showing the first eight; more decompositions exist.
