Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709942, here are decompositions:

11 + 8709931 = 8709942
13 + 8709929 = 8709942
23 + 8709919 = 8709942
29 + 8709913 = 8709942
71 + 8709871 = 8709942
103 + 8709839 = 8709942
149 + 8709793 = 8709942
191 + 8709751 = 8709942

Showing the first eight; more decompositions exist.
