Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733638, here are decompositions:

19 + 8733619 = 8733638
97 + 8733541 = 8733638
127 + 8733511 = 8733638
241 + 8733397 = 8733638
337 + 8733301 = 8733638
367 + 8733271 = 8733638
379 + 8733259 = 8733638
751 + 8732887 = 8733638

Showing the first eight; more decompositions exist.
