Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756140, here are decompositions:

11 + 8756129 = 8756140
23 + 8756117 = 8756140
89 + 8756051 = 8756140
101 + 8756039 = 8756140
131 + 8756009 = 8756140
149 + 8755991 = 8756140
167 + 8755973 = 8756140
227 + 8755913 = 8756140

Showing the first eight; more decompositions exist.
