Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724668, here are decompositions:

19 + 8724649 = 8724668
37 + 8724631 = 8724668
67 + 8724601 = 8724668
79 + 8724589 = 8724668
109 + 8724559 = 8724668
157 + 8724511 = 8724668
181 + 8724487 = 8724668
349 + 8724319 = 8724668

Showing the first eight; more decompositions exist.
