Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700400, here are decompositions:

17 + 8700383 = 8700400
47 + 8700353 = 8700400
101 + 8700299 = 8700400
113 + 8700287 = 8700400
239 + 8700161 = 8700400
353 + 8700047 = 8700400
389 + 8700011 = 8700400
419 + 8699981 = 8700400

Showing the first eight; more decompositions exist.
