Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711620, here are decompositions:

3 + 8711617 = 8711620
17 + 8711603 = 8711620
59 + 8711561 = 8711620
131 + 8711489 = 8711620
173 + 8711447 = 8711620
233 + 8711387 = 8711620
257 + 8711363 = 8711620
263 + 8711357 = 8711620

Showing the first eight; more decompositions exist.
