Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708920, here are decompositions:

71 + 8708849 = 8708920
89 + 8708831 = 8708920
113 + 8708807 = 8708920
179 + 8708741 = 8708920
257 + 8708663 = 8708920
263 + 8708657 = 8708920
281 + 8708639 = 8708920
293 + 8708627 = 8708920

Showing the first eight; more decompositions exist.
