Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651292, here are decompositions:

11 + 8651281 = 8651292
31 + 8651261 = 8651292
53 + 8651239 = 8651292
59 + 8651233 = 8651292
61 + 8651231 = 8651292
101 + 8651191 = 8651292
103 + 8651189 = 8651292
113 + 8651179 = 8651292

Showing the first eight; more decompositions exist.
