Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658998, here are decompositions:

37 + 8658961 = 8658998
67 + 8658931 = 8658998
79 + 8658919 = 8658998
151 + 8658847 = 8658998
241 + 8658757 = 8658998
379 + 8658619 = 8658998
409 + 8658589 = 8658998
421 + 8658577 = 8658998

Showing the first eight; more decompositions exist.
