Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613800, here are decompositions:

3 + 8613797 = 8613800
43 + 8613757 = 8613800
61 + 8613739 = 8613800
67 + 8613733 = 8613800
229 + 8613571 = 8613800
241 + 8613559 = 8613800
271 + 8613529 = 8613800
337 + 8613463 = 8613800

Showing the first eight; more decompositions exist.
