Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711408, here are decompositions:

7 + 8711401 = 8711408
31 + 8711377 = 8711408
61 + 8711347 = 8711408
229 + 8711179 = 8711408
271 + 8711137 = 8711408
337 + 8711071 = 8711408
397 + 8711011 = 8711408
499 + 8710909 = 8711408

Showing the first eight; more decompositions exist.
