Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658958, here are decompositions:

17 + 8658941 = 8658958
47 + 8658911 = 8658958
71 + 8658887 = 8658958
89 + 8658869 = 8658958
281 + 8658677 = 8658958
389 + 8658569 = 8658958
431 + 8658527 = 8658958
587 + 8658371 = 8658958

Showing the first eight; more decompositions exist.
