Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700380, here are decompositions:

19 + 8700361 = 8700380
97 + 8700283 = 8700380
127 + 8700253 = 8700380
211 + 8700169 = 8700380
349 + 8700031 = 8700380
373 + 8700007 = 8700380
379 + 8700001 = 8700380
421 + 8699959 = 8700380

Showing the first eight; more decompositions exist.
