Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031868, here are decompositions:

31 + 1031837 = 1031868
37 + 1031831 = 1031868
59 + 1031809 = 1031868
107 + 1031761 = 1031868
109 + 1031759 = 1031868
127 + 1031741 = 1031868
137 + 1031731 = 1031868
139 + 1031729 = 1031868

Showing the first eight; more decompositions exist.
