Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727972, here are decompositions:

41 + 8727931 = 8727972
59 + 8727913 = 8727972
73 + 8727899 = 8727972
101 + 8727871 = 8727972
163 + 8727809 = 8727972
181 + 8727791 = 8727972
193 + 8727779 = 8727972
199 + 8727773 = 8727972

Showing the first eight; more decompositions exist.
