Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700890, here are decompositions:

19 + 8700871 = 8700890
73 + 8700817 = 8700890
97 + 8700793 = 8700890
139 + 8700751 = 8700890
181 + 8700709 = 8700890
193 + 8700697 = 8700890
241 + 8700649 = 8700890
379 + 8700511 = 8700890

Showing the first eight; more decompositions exist.
