Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026730, here are decompositions:

53 + 1026677 = 1026730
137 + 1026593 = 1026730
149 + 1026581 = 1026730
167 + 1026563 = 1026730
251 + 1026479 = 1026730
281 + 1026449 = 1026730
317 + 1026413 = 1026730
347 + 1026383 = 1026730

Showing the first eight; more decompositions exist.
