Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612168, here are decompositions:

79 + 8612089 = 8612168
109 + 8612059 = 8612168
157 + 8612011 = 8612168
181 + 8611987 = 8612168
199 + 8611969 = 8612168
277 + 8611891 = 8612168
349 + 8611819 = 8612168
379 + 8611789 = 8612168

Showing the first eight; more decompositions exist.
