Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740998, here are decompositions:

5 + 8740993 = 8740998
47 + 8740951 = 8740998
59 + 8740939 = 8740998
107 + 8740891 = 8740998
127 + 8740871 = 8740998
131 + 8740867 = 8740998
139 + 8740859 = 8740998
157 + 8740841 = 8740998

Showing the first eight; more decompositions exist.
