Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735020, here are decompositions:

101 + 8734919 = 8735020
137 + 8734883 = 8735020
167 + 8734853 = 8735020
179 + 8734841 = 8735020
197 + 8734823 = 8735020
251 + 8734769 = 8735020
263 + 8734757 = 8735020
443 + 8734577 = 8735020

Showing the first eight; more decompositions exist.
