Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712258, here are decompositions:

29 + 8712229 = 8712258
31 + 8712227 = 8712258
89 + 8712169 = 8712258
101 + 8712157 = 8712258
109 + 8712149 = 8712258
167 + 8712091 = 8712258
199 + 8712059 = 8712258
229 + 8712029 = 8712258

Showing the first eight; more decompositions exist.
