Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611164, here are decompositions:

13 + 8611151 = 8611164
17 + 8611147 = 8611164
31 + 8611133 = 8611164
47 + 8611117 = 8611164
101 + 8611063 = 8611164
127 + 8611037 = 8611164
131 + 8611033 = 8611164
167 + 8610997 = 8611164

Showing the first eight; more decompositions exist.
