Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746990, here are decompositions:

11 + 8746979 = 8746990
23 + 8746967 = 8746990
41 + 8746949 = 8746990
53 + 8746937 = 8746990
71 + 8746919 = 8746990
179 + 8746811 = 8746990
191 + 8746799 = 8746990
233 + 8746757 = 8746990

Showing the first eight; more decompositions exist.
