Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732540, here are decompositions:

67 + 8732473 = 8732540
79 + 8732461 = 8732540
109 + 8732431 = 8732540
241 + 8732299 = 8732540
283 + 8732257 = 8732540
331 + 8732209 = 8732540
547 + 8731993 = 8732540
601 + 8731939 = 8732540

Showing the first eight; more decompositions exist.
