Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031860, here are decompositions:

23 + 1031837 = 1031860
29 + 1031831 = 1031860
47 + 1031813 = 1031860
101 + 1031759 = 1031860
107 + 1031753 = 1031860
131 + 1031729 = 1031860
191 + 1031669 = 1031860
227 + 1031633 = 1031860

Showing the first eight; more decompositions exist.
