Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700780, here are decompositions:

7 + 8700773 = 8700780
13 + 8700767 = 8700780
29 + 8700751 = 8700780
59 + 8700721 = 8700780
71 + 8700709 = 8700780
83 + 8700697 = 8700780
131 + 8700649 = 8700780
181 + 8700599 = 8700780

Showing the first eight; more decompositions exist.
