Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708878, here are decompositions:

29 + 8708849 = 8708878
47 + 8708831 = 8708878
71 + 8708807 = 8708878
137 + 8708741 = 8708878
239 + 8708639 = 8708878
251 + 8708627 = 8708878
257 + 8708621 = 8708878
359 + 8708519 = 8708878

Showing the first eight; more decompositions exist.
