Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711800, here are decompositions:

3 + 8711797 = 8711800
17 + 8711783 = 8711800
23 + 8711777 = 8711800
59 + 8711741 = 8711800
131 + 8711669 = 8711800
173 + 8711627 = 8711800
179 + 8711621 = 8711800
197 + 8711603 = 8711800

Showing the first eight; more decompositions exist.
