Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700980, here are decompositions:

109 + 8700871 = 8700980
163 + 8700817 = 8700980
181 + 8700799 = 8700980
229 + 8700751 = 8700980
271 + 8700709 = 8700980
283 + 8700697 = 8700980
331 + 8700649 = 8700980
433 + 8700547 = 8700980

Showing the first eight; more decompositions exist.
