Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715844, here are decompositions:

3 + 8715841 = 8715844
83 + 8715761 = 8715844
113 + 8715731 = 8715844
173 + 8715671 = 8715844
191 + 8715653 = 8715844
197 + 8715647 = 8715844
227 + 8715617 = 8715844
257 + 8715587 = 8715844

Showing the first eight; more decompositions exist.
