Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985730, here are decompositions:

7 + 985723 = 985730
73 + 985657 = 985730
199 + 985531 = 985730
211 + 985519 = 985730
283 + 985447 = 985730
313 + 985417 = 985730
331 + 985399 = 985730
379 + 985351 = 985730

Showing the first eight; more decompositions exist.
