Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671400, here are decompositions:

7 + 8671393 = 8671400
19 + 8671381 = 8671400
37 + 8671363 = 8671400
61 + 8671339 = 8671400
79 + 8671321 = 8671400
109 + 8671291 = 8671400
151 + 8671249 = 8671400
181 + 8671219 = 8671400

Showing the first eight; more decompositions exist.
