Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712238, here are decompositions:

5 + 8712233 = 8712238
11 + 8712227 = 8712238
71 + 8712167 = 8712238
89 + 8712149 = 8712238
179 + 8712059 = 8712238
251 + 8711987 = 8712238
317 + 8711921 = 8712238
389 + 8711849 = 8712238

Showing the first eight; more decompositions exist.
