Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711380, here are decompositions:

3 + 8711377 = 8711380
17 + 8711363 = 8711380
23 + 8711357 = 8711380
47 + 8711333 = 8711380
113 + 8711267 = 8711380
191 + 8711189 = 8711380
239 + 8711141 = 8711380
263 + 8711117 = 8711380

Showing the first eight; more decompositions exist.
