Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629900, here are decompositions:

11 + 8629889 = 8629900
17 + 8629883 = 8629900
53 + 8629847 = 8629900
137 + 8629763 = 8629900
239 + 8629661 = 8629900
263 + 8629637 = 8629900
317 + 8629583 = 8629900
467 + 8629433 = 8629900

Showing the first eight; more decompositions exist.
