Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731472, here are decompositions:

103 + 8731369 = 8731472
109 + 8731363 = 8731472
151 + 8731321 = 8731472
163 + 8731309 = 8731472
223 + 8731249 = 8731472
241 + 8731231 = 8731472
271 + 8731201 = 8731472
331 + 8731141 = 8731472

Showing the first eight; more decompositions exist.
