Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609402, here are decompositions:

31 + 8609371 = 8609402
79 + 8609323 = 8609402
163 + 8609239 = 8609402
229 + 8609173 = 8609402
283 + 8609119 = 8609402
379 + 8609023 = 8609402
523 + 8608879 = 8609402
541 + 8608861 = 8609402

Showing the first eight; more decompositions exist.
