Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711438, here are decompositions:

37 + 8711401 = 8711438
61 + 8711377 = 8711438
79 + 8711359 = 8711438
277 + 8711161 = 8711438
367 + 8711071 = 8711438
499 + 8710939 = 8711438
691 + 8710747 = 8711438
709 + 8710729 = 8711438

Showing the first eight; more decompositions exist.
