Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724770, here are decompositions:

31 + 8724739 = 8724770
73 + 8724697 = 8724770
127 + 8724643 = 8724770
139 + 8724631 = 8724770
151 + 8724619 = 8724770
181 + 8724589 = 8724770
211 + 8724559 = 8724770
277 + 8724493 = 8724770

Showing the first eight; more decompositions exist.
