Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724846, here are decompositions:

19 + 8724827 = 8724846
43 + 8724803 = 8724846
47 + 8724799 = 8724846
59 + 8724787 = 8724846
107 + 8724739 = 8724846
127 + 8724719 = 8724846
149 + 8724697 = 8724846
197 + 8724649 = 8724846

Showing the first eight; more decompositions exist.
