Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700940, here are decompositions:

29 + 8700911 = 8700940
47 + 8700893 = 8700940
71 + 8700869 = 8700940
107 + 8700833 = 8700940
113 + 8700827 = 8700940
167 + 8700773 = 8700940
173 + 8700767 = 8700940
359 + 8700581 = 8700940

Showing the first eight; more decompositions exist.
