Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727998, here are decompositions:

61 + 8727937 = 8727998
67 + 8727931 = 8727998
127 + 8727871 = 8727998
241 + 8727757 = 8727998
271 + 8727727 = 8727998
379 + 8727619 = 8727998
397 + 8727601 = 8727998
421 + 8727577 = 8727998

Showing the first eight; more decompositions exist.
