Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709900, here are decompositions:

29 + 8709871 = 8709900
61 + 8709839 = 8709900
79 + 8709821 = 8709900
83 + 8709817 = 8709900
107 + 8709793 = 8709900
149 + 8709751 = 8709900
163 + 8709737 = 8709900
179 + 8709721 = 8709900

Showing the first eight; more decompositions exist.
