Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605998, here are decompositions:

59 + 8605939 = 8605998
67 + 8605931 = 8605998
127 + 8605871 = 8605998
197 + 8605801 = 8605998
307 + 8605691 = 8605998
389 + 8605609 = 8605998
397 + 8605601 = 8605998
421 + 8605577 = 8605998

Showing the first eight; more decompositions exist.
