Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700020, here are decompositions:

13 + 8700007 = 8700020
19 + 8700001 = 8700020
61 + 8699959 = 8700020
67 + 8699953 = 8700020
73 + 8699947 = 8700020
97 + 8699923 = 8700020
103 + 8699917 = 8700020
127 + 8699893 = 8700020

Showing the first eight; more decompositions exist.
