Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731604, here are decompositions:

73 + 8731531 = 8731604
103 + 8731501 = 8731604
127 + 8731477 = 8731604
157 + 8731447 = 8731604
223 + 8731381 = 8731604
241 + 8731363 = 8731604
283 + 8731321 = 8731604
373 + 8731231 = 8731604

Showing the first eight; more decompositions exist.
