Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731562, here are decompositions:

31 + 8731531 = 8731562
61 + 8731501 = 8731562
181 + 8731381 = 8731562
193 + 8731369 = 8731562
199 + 8731363 = 8731562
223 + 8731339 = 8731562
241 + 8731321 = 8731562
313 + 8731249 = 8731562

Showing the first eight; more decompositions exist.
