Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658940, here are decompositions:

29 + 8658911 = 8658940
47 + 8658893 = 8658940
53 + 8658887 = 8658940
71 + 8658869 = 8658940
167 + 8658773 = 8658940
263 + 8658677 = 8658940
281 + 8658659 = 8658940
359 + 8658581 = 8658940

Showing the first eight; more decompositions exist.
