Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609142, here are decompositions:

5 + 8609137 = 8609142
13 + 8609129 = 8609142
23 + 8609119 = 8609142
43 + 8609099 = 8609142
79 + 8609063 = 8609142
211 + 8608931 = 8609142
229 + 8608913 = 8609142
233 + 8608909 = 8609142

Showing the first eight; more decompositions exist.
