Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027738, here are decompositions:

11 + 1027727 = 1027738
59 + 1027679 = 1027738
191 + 1027547 = 1027738
251 + 1027487 = 1027738
311 + 1027427 = 1027738
317 + 1027421 = 1027738
347 + 1027391 = 1027738
419 + 1027319 = 1027738

Showing the first eight; more decompositions exist.
