Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711842, here are decompositions:

59 + 8711783 = 8711842
101 + 8711741 = 8711842
173 + 8711669 = 8711842
239 + 8711603 = 8711842
281 + 8711561 = 8711842
353 + 8711489 = 8711842
443 + 8711399 = 8711842
479 + 8711363 = 8711842

Showing the first eight; more decompositions exist.
