Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704138, here are decompositions:

17 + 8704121 = 8704138
71 + 8704067 = 8704138
89 + 8704049 = 8704138
167 + 8703971 = 8704138
227 + 8703911 = 8704138
239 + 8703899 = 8704138
419 + 8703719 = 8704138
479 + 8703659 = 8704138

Showing the first eight; more decompositions exist.
