Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730028, here are decompositions:

29 + 8729999 = 8730028
89 + 8729939 = 8730028
179 + 8729849 = 8730028
191 + 8729837 = 8730028
227 + 8729801 = 8730028
311 + 8729717 = 8730028
317 + 8729711 = 8730028
347 + 8729681 = 8730028

Showing the first eight; more decompositions exist.
