Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609138, here are decompositions:

19 + 8609119 = 8609138
61 + 8609077 = 8609138
229 + 8608909 = 8609138
277 + 8608861 = 8609138
337 + 8608801 = 8609138
367 + 8608771 = 8609138
379 + 8608759 = 8609138
541 + 8608597 = 8609138

Showing the first eight; more decompositions exist.
