Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722850, here are decompositions:

61 + 8722789 = 8722850
139 + 8722711 = 8722850
229 + 8722621 = 8722850
373 + 8722477 = 8722850
379 + 8722471 = 8722850
421 + 8722429 = 8722850
457 + 8722393 = 8722850
547 + 8722303 = 8722850

Showing the first eight; more decompositions exist.
