Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722802, here are decompositions:

3 + 8722799 = 8722802
13 + 8722789 = 8722802
181 + 8722621 = 8722802
199 + 8722603 = 8722802
331 + 8722471 = 8722802
373 + 8722429 = 8722802
379 + 8722423 = 8722802
409 + 8722393 = 8722802

Showing the first eight; more decompositions exist.
