Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731752, here are decompositions:

31 + 8731721 = 8731752
41 + 8731711 = 8731752
53 + 8731699 = 8731752
79 + 8731673 = 8731752
109 + 8731643 = 8731752
173 + 8731579 = 8731752
181 + 8731571 = 8731752
223 + 8731529 = 8731752

Showing the first eight; more decompositions exist.
