Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731532, here are decompositions:

3 + 8731529 = 8731532
31 + 8731501 = 8731532
151 + 8731381 = 8731532
163 + 8731369 = 8731532
193 + 8731339 = 8731532
211 + 8731321 = 8731532
223 + 8731309 = 8731532
283 + 8731249 = 8731532

Showing the first eight; more decompositions exist.
