Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729158, here are decompositions:

17 + 8729141 = 8729158
41 + 8729117 = 8729158
59 + 8729099 = 8729158
101 + 8729057 = 8729158
107 + 8729051 = 8729158
257 + 8728901 = 8729158
401 + 8728757 = 8729158
467 + 8728691 = 8729158

Showing the first eight; more decompositions exist.
