Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712154, here are decompositions:

5 + 8712149 = 8712154
41 + 8712113 = 8712154
137 + 8712017 = 8712154
167 + 8711987 = 8712154
233 + 8711921 = 8712154
257 + 8711897 = 8712154
593 + 8711561 = 8712154
653 + 8711501 = 8712154

Showing the first eight; more decompositions exist.
