Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619800, here are decompositions:

3 + 8619797 = 8619800
139 + 8619661 = 8619800
151 + 8619649 = 8619800
199 + 8619601 = 8619800
331 + 8619469 = 8619800
367 + 8619433 = 8619800
373 + 8619427 = 8619800
379 + 8619421 = 8619800

Showing the first eight; more decompositions exist.
