Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709930, here are decompositions:

11 + 8709919 = 8709930
17 + 8709913 = 8709930
59 + 8709871 = 8709930
109 + 8709821 = 8709930
113 + 8709817 = 8709930
137 + 8709793 = 8709930
149 + 8709781 = 8709930
179 + 8709751 = 8709930

Showing the first eight; more decompositions exist.
