Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731232, here are decompositions:

19 + 8731213 = 8731232
31 + 8731201 = 8731232
79 + 8731153 = 8731232
163 + 8731069 = 8731232
193 + 8731039 = 8731232
283 + 8730949 = 8731232
313 + 8730919 = 8731232
331 + 8730901 = 8731232

Showing the first eight; more decompositions exist.
