Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700678, here are decompositions:

29 + 8700649 = 8700678
79 + 8700599 = 8700678
89 + 8700589 = 8700678
97 + 8700581 = 8700678
131 + 8700547 = 8700678
139 + 8700539 = 8700678
149 + 8700529 = 8700678
157 + 8700521 = 8700678

Showing the first eight; more decompositions exist.
