Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724968, here are decompositions:

19 + 8724949 = 8724968
97 + 8724871 = 8724968
181 + 8724787 = 8724968
229 + 8724739 = 8724968
271 + 8724697 = 8724968
337 + 8724631 = 8724968
349 + 8724619 = 8724968
367 + 8724601 = 8724968

Showing the first eight; more decompositions exist.
