Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039818, here are decompositions:

19 + 1039799 = 1039818
29 + 1039789 = 1039818
137 + 1039681 = 1039818
151 + 1039667 = 1039818
167 + 1039651 = 1039818
211 + 1039607 = 1039818
281 + 1039537 = 1039818
337 + 1039481 = 1039818

Showing the first eight; more decompositions exist.
