Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704990, here are decompositions:

11 + 8704979 = 8704990
17 + 8704973 = 8704990
23 + 8704967 = 8704990
53 + 8704937 = 8704990
101 + 8704889 = 8704990
137 + 8704853 = 8704990
179 + 8704811 = 8704990
233 + 8704757 = 8704990

Showing the first eight; more decompositions exist.
