Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693990, here are decompositions:

7 + 8693983 = 8693990
31 + 8693959 = 8693990
43 + 8693947 = 8693990
73 + 8693917 = 8693990
79 + 8693911 = 8693990
223 + 8693767 = 8693990
313 + 8693677 = 8693990
337 + 8693653 = 8693990

Showing the first eight; more decompositions exist.
