Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710870, here are decompositions:

23 + 8710847 = 8710870
41 + 8710829 = 8710870
89 + 8710781 = 8710870
137 + 8710733 = 8710870
167 + 8710703 = 8710870
191 + 8710679 = 8710870
239 + 8710631 = 8710870
281 + 8710589 = 8710870

Showing the first eight; more decompositions exist.
