Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731996, here are decompositions:

3 + 8731993 = 8731996
5 + 8731991 = 8731996
17 + 8731979 = 8731996
59 + 8731937 = 8731996
83 + 8731913 = 8731996
89 + 8731907 = 8731996
137 + 8731859 = 8731996
179 + 8731817 = 8731996

Showing the first eight; more decompositions exist.
