Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729432, here are decompositions:

3 + 8729429 = 8729432
31 + 8729401 = 8729432
43 + 8729389 = 8729432
109 + 8729323 = 8729432
193 + 8729239 = 8729432
211 + 8729221 = 8729432
241 + 8729191 = 8729432
373 + 8729059 = 8729432

Showing the first eight; more decompositions exist.
