Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609242, here are decompositions:

3 + 8609239 = 8609242
113 + 8609129 = 8609242
149 + 8609093 = 8609242
179 + 8609063 = 8609242
269 + 8608973 = 8609242
311 + 8608931 = 8609242
353 + 8608889 = 8609242
401 + 8608841 = 8609242

Showing the first eight; more decompositions exist.
