Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732428, here are decompositions:

11 + 8732417 = 8732428
17 + 8732411 = 8732428
59 + 8732369 = 8732428
137 + 8732291 = 8732428
167 + 8732261 = 8732428
227 + 8732201 = 8732428
239 + 8732189 = 8732428
269 + 8732159 = 8732428

Showing the first eight; more decompositions exist.
