Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031878, here are decompositions:

41 + 1031837 = 1031878
47 + 1031831 = 1031878
137 + 1031741 = 1031878
149 + 1031729 = 1031878
269 + 1031609 = 1031878
317 + 1031561 = 1031878
347 + 1031531 = 1031878
389 + 1031489 = 1031878

Showing the first eight; more decompositions exist.
