Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731998, here are decompositions:

5 + 8731993 = 8731998
7 + 8731991 = 8731998
17 + 8731981 = 8731998
19 + 8731979 = 8731998
47 + 8731951 = 8731998
59 + 8731939 = 8731998
61 + 8731937 = 8731998
97 + 8731901 = 8731998

Showing the first eight; more decompositions exist.
