Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711818, here are decompositions:

41 + 8711777 = 8711818
149 + 8711669 = 8711818
191 + 8711627 = 8711818
197 + 8711621 = 8711818
257 + 8711561 = 8711818
317 + 8711501 = 8711818
419 + 8711399 = 8711818
431 + 8711387 = 8711818

Showing the first eight; more decompositions exist.
