Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747958, here are decompositions:

17 + 8747941 = 8747958
29 + 8747929 = 8747958
31 + 8747927 = 8747958
41 + 8747917 = 8747958
67 + 8747891 = 8747958
101 + 8747857 = 8747958
127 + 8747831 = 8747958
139 + 8747819 = 8747958

Showing the first eight; more decompositions exist.
