Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711824, here are decompositions:

3 + 8711821 = 8711824
41 + 8711783 = 8711824
47 + 8711777 = 8711824
83 + 8711741 = 8711824
167 + 8711657 = 8711824
197 + 8711627 = 8711824
263 + 8711561 = 8711824
281 + 8711543 = 8711824

Showing the first eight; more decompositions exist.
