Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711392, here are decompositions:

5 + 8711387 = 8711392
29 + 8711363 = 8711392
59 + 8711333 = 8711392
233 + 8711159 = 8711392
251 + 8711141 = 8711392
311 + 8711081 = 8711392
359 + 8711033 = 8711392
383 + 8711009 = 8711392

Showing the first eight; more decompositions exist.
