Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709042, here are decompositions:

71 + 8708971 = 8709042
73 + 8708969 = 8709042
79 + 8708963 = 8709042
131 + 8708911 = 8709042
149 + 8708893 = 8709042
193 + 8708849 = 8709042
211 + 8708831 = 8709042
239 + 8708803 = 8709042

Showing the first eight; more decompositions exist.
