Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707678, here are decompositions:

17 + 8707661 = 8707678
29 + 8707649 = 8707678
47 + 8707631 = 8707678
71 + 8707607 = 8707678
257 + 8707421 = 8707678
389 + 8707289 = 8707678
401 + 8707277 = 8707678
587 + 8707091 = 8707678

Showing the first eight; more decompositions exist.
