Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609140, here are decompositions:

3 + 8609137 = 8609140
11 + 8609129 = 8609140
41 + 8609099 = 8609140
47 + 8609093 = 8609140
53 + 8609087 = 8609140
167 + 8608973 = 8609140
227 + 8608913 = 8609140
233 + 8608907 = 8609140

Showing the first eight; more decompositions exist.
