Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710978, here are decompositions:

5 + 8710973 = 8710978
11 + 8710967 = 8710978
131 + 8710847 = 8710978
149 + 8710829 = 8710978
197 + 8710781 = 8710978
251 + 8710727 = 8710978
347 + 8710631 = 8710978
389 + 8710589 = 8710978

Showing the first eight; more decompositions exist.
