Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711490, here are decompositions:

23 + 8711467 = 8711490
43 + 8711447 = 8711490
89 + 8711401 = 8711490
103 + 8711387 = 8711490
107 + 8711383 = 8711490
113 + 8711377 = 8711490
127 + 8711363 = 8711490
131 + 8711359 = 8711490

Showing the first eight; more decompositions exist.
