Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724768, here are decompositions:

29 + 8724739 = 8724768
47 + 8724721 = 8724768
71 + 8724697 = 8724768
127 + 8724641 = 8724768
137 + 8724631 = 8724768
149 + 8724619 = 8724768
167 + 8724601 = 8724768
179 + 8724589 = 8724768

Showing the first eight; more decompositions exist.
