Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729504, here are decompositions:

13 + 8729491 = 8729504
37 + 8729467 = 8729504
103 + 8729401 = 8729504
181 + 8729323 = 8729504
283 + 8729221 = 8729504
313 + 8729191 = 8729504
331 + 8729173 = 8729504
373 + 8729131 = 8729504

Showing the first eight; more decompositions exist.
