Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658974, here are decompositions:

13 + 8658961 = 8658974
31 + 8658943 = 8658974
43 + 8658931 = 8658974
97 + 8658877 = 8658974
127 + 8658847 = 8658974
277 + 8658697 = 8658974
397 + 8658577 = 8658974
421 + 8658553 = 8658974

Showing the first eight; more decompositions exist.
