Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711442, here are decompositions:

41 + 8711401 = 8711442
43 + 8711399 = 8711442
59 + 8711383 = 8711442
79 + 8711363 = 8711442
83 + 8711359 = 8711442
109 + 8711333 = 8711442
263 + 8711179 = 8711442
281 + 8711161 = 8711442

Showing the first eight; more decompositions exist.
