Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729132, here are decompositions:

73 + 8729059 = 8729132
79 + 8729053 = 8729132
163 + 8728969 = 8729132
211 + 8728921 = 8729132
229 + 8728903 = 8729132
283 + 8728849 = 8729132
421 + 8728711 = 8729132
523 + 8728609 = 8729132

Showing the first eight; more decompositions exist.
