Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611158, here are decompositions:

7 + 8611151 = 8611158
11 + 8611147 = 8611158
19 + 8611139 = 8611158
41 + 8611117 = 8611158
197 + 8610961 = 8611158
239 + 8610919 = 8611158
277 + 8610881 = 8611158
307 + 8610851 = 8611158

Showing the first eight; more decompositions exist.
