Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711990, here are decompositions:

3 + 8711987 = 8711990
19 + 8711971 = 8711990
37 + 8711953 = 8711990
103 + 8711887 = 8711990
127 + 8711863 = 8711990
139 + 8711851 = 8711990
193 + 8711797 = 8711990
223 + 8711767 = 8711990

Showing the first eight; more decompositions exist.
