Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694990, here are decompositions:

19 + 8694971 = 8694990
23 + 8694967 = 8694990
43 + 8694947 = 8694990
149 + 8694841 = 8694990
151 + 8694839 = 8694990
167 + 8694823 = 8694990
193 + 8694797 = 8694990
197 + 8694793 = 8694990

Showing the first eight; more decompositions exist.
