Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031838, here are decompositions:

7 + 1031831 = 1031838
29 + 1031809 = 1031838
79 + 1031759 = 1031838
97 + 1031741 = 1031838
107 + 1031731 = 1031838
109 + 1031729 = 1031838
131 + 1031707 = 1031838
229 + 1031609 = 1031838

Showing the first eight; more decompositions exist.
