Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711578, here are decompositions:

17 + 8711561 = 8711578
89 + 8711489 = 8711578
131 + 8711447 = 8711578
179 + 8711399 = 8711578
191 + 8711387 = 8711578
311 + 8711267 = 8711578
389 + 8711189 = 8711578
419 + 8711159 = 8711578

Showing the first eight; more decompositions exist.
