Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027838, here are decompositions:

61 + 1027777 = 1027838
79 + 1027759 = 1027838
151 + 1027687 = 1027838
241 + 1027597 = 1027838
271 + 1027567 = 1027838
349 + 1027489 = 1027838
367 + 1027471 = 1027838
379 + 1027459 = 1027838

Showing the first eight; more decompositions exist.
