Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658942, here are decompositions:

11 + 8658931 = 8658942
23 + 8658919 = 8658942
31 + 8658911 = 8658942
73 + 8658869 = 8658942
113 + 8658829 = 8658942
233 + 8658709 = 8658942
263 + 8658679 = 8658942
269 + 8658673 = 8658942

Showing the first eight; more decompositions exist.
