Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729382, here are decompositions:

59 + 8729323 = 8729382
73 + 8729309 = 8729382
139 + 8729243 = 8729382
163 + 8729219 = 8729382
191 + 8729191 = 8729382
199 + 8729183 = 8729382
241 + 8729141 = 8729382
251 + 8729131 = 8729382

Showing the first eight; more decompositions exist.
