Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045812, here are decompositions:

11 + 1045801 = 1045812
13 + 1045799 = 1045812
73 + 1045739 = 1045812
83 + 1045729 = 1045812
149 + 1045663 = 1045812
179 + 1045633 = 1045812
191 + 1045621 = 1045812
239 + 1045573 = 1045812

Showing the first eight; more decompositions exist.
