Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700408, here are decompositions:

7 + 8700401 = 8700408
47 + 8700361 = 8700408
109 + 8700299 = 8700408
127 + 8700281 = 8700408
151 + 8700257 = 8700408
239 + 8700169 = 8700408
337 + 8700071 = 8700408
349 + 8700059 = 8700408

Showing the first eight; more decompositions exist.
