Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722730, here are decompositions:

19 + 8722711 = 8722730
109 + 8722621 = 8722730
127 + 8722603 = 8722730
271 + 8722459 = 8722730
283 + 8722447 = 8722730
307 + 8722423 = 8722730
337 + 8722393 = 8722730
397 + 8722333 = 8722730

Showing the first eight; more decompositions exist.
