Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700420, here are decompositions:

13 + 8700407 = 8700420
19 + 8700401 = 8700420
37 + 8700383 = 8700420
59 + 8700361 = 8700420
67 + 8700353 = 8700420
137 + 8700283 = 8700420
139 + 8700281 = 8700420
163 + 8700257 = 8700420

Showing the first eight; more decompositions exist.
