Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647706, here are decompositions:

7 + 8647699 = 8647706
127 + 8647579 = 8647706
139 + 8647567 = 8647706
313 + 8647393 = 8647706
337 + 8647369 = 8647706
433 + 8647273 = 8647706
523 + 8647183 = 8647706
577 + 8647129 = 8647706

Showing the first eight; more decompositions exist.
