Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731550, here are decompositions:

19 + 8731531 = 8731550
73 + 8731477 = 8731550
103 + 8731447 = 8731550
181 + 8731369 = 8731550
211 + 8731339 = 8731550
229 + 8731321 = 8731550
241 + 8731309 = 8731550
337 + 8731213 = 8731550

Showing the first eight; more decompositions exist.
