Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045884, here are decompositions:

43 + 1045841 = 1045884
83 + 1045801 = 1045884
157 + 1045727 = 1045884
193 + 1045691 = 1045884
233 + 1045651 = 1045884
241 + 1045643 = 1045884
251 + 1045633 = 1045884
263 + 1045621 = 1045884

Showing the first eight; more decompositions exist.
