Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729406, here are decompositions:

5 + 8729401 = 8729406
17 + 8729389 = 8729406
73 + 8729333 = 8729406
79 + 8729327 = 8729406
83 + 8729323 = 8729406
89 + 8729317 = 8729406
97 + 8729309 = 8729406
157 + 8729249 = 8729406

Showing the first eight; more decompositions exist.
