Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712208, here are decompositions:

41 + 8712167 = 8712208
59 + 8712149 = 8712208
149 + 8712059 = 8712208
179 + 8712029 = 8712208
191 + 8712017 = 8712208
257 + 8711951 = 8712208
311 + 8711897 = 8712208
359 + 8711849 = 8712208

Showing the first eight; more decompositions exist.
