Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731724, here are decompositions:

3 + 8731721 = 8731724
13 + 8731711 = 8731724
37 + 8731687 = 8731724
97 + 8731627 = 8731724
193 + 8731531 = 8731724
223 + 8731501 = 8731724
277 + 8731447 = 8731724
307 + 8731417 = 8731724

Showing the first eight; more decompositions exist.
