Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611284, here are decompositions:

23 + 8611261 = 8611284
37 + 8611247 = 8611284
83 + 8611201 = 8611284
103 + 8611181 = 8611284
137 + 8611147 = 8611284
151 + 8611133 = 8611284
167 + 8611117 = 8611284
251 + 8611033 = 8611284

Showing the first eight; more decompositions exist.
