Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627900, here are decompositions:

3 + 8627897 = 8627900
7 + 8627893 = 8627900
67 + 8627833 = 8627900
199 + 8627701 = 8627900
283 + 8627617 = 8627900
331 + 8627569 = 8627900
367 + 8627533 = 8627900
373 + 8627527 = 8627900

Showing the first eight; more decompositions exist.
