Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710872, here are decompositions:

43 + 8710829 = 8710872
101 + 8710771 = 8710872
139 + 8710733 = 8710872
173 + 8710699 = 8710872
179 + 8710693 = 8710872
193 + 8710679 = 8710872
223 + 8710649 = 8710872
239 + 8710633 = 8710872

Showing the first eight; more decompositions exist.
