Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720338, here are decompositions:

17 + 8720321 = 8720338
149 + 8720189 = 8720338
167 + 8720171 = 8720338
227 + 8720111 = 8720338
251 + 8720087 = 8720338
257 + 8720081 = 8720338
281 + 8720057 = 8720338
311 + 8720027 = 8720338

Showing the first eight; more decompositions exist.
