Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729372, here are decompositions:

151 + 8729221 = 8729372
181 + 8729191 = 8729372
193 + 8729179 = 8729372
199 + 8729173 = 8729372
241 + 8729131 = 8729372
313 + 8729059 = 8729372
409 + 8728963 = 8729372
523 + 8728849 = 8729372

Showing the first eight; more decompositions exist.
