Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724698, here are decompositions:

67 + 8724631 = 8724698
79 + 8724619 = 8724698
97 + 8724601 = 8724698
109 + 8724589 = 8724698
139 + 8724559 = 8724698
211 + 8724487 = 8724698
277 + 8724421 = 8724698
379 + 8724319 = 8724698

Showing the first eight; more decompositions exist.
