Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611128, here are decompositions:

11 + 8611117 = 8611128
131 + 8610997 = 8611128
167 + 8610961 = 8611128
191 + 8610937 = 8611128
257 + 8610871 = 8611128
277 + 8610851 = 8611128
389 + 8610739 = 8611128
397 + 8610731 = 8611128

Showing the first eight; more decompositions exist.
