Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042992, here are decompositions:

31 + 1042961 = 1042992
43 + 1042949 = 1042992
61 + 1042931 = 1042992
89 + 1042903 = 1042992
131 + 1042861 = 1042992
163 + 1042829 = 1042992
173 + 1042819 = 1042992
193 + 1042799 = 1042992

Showing the first eight; more decompositions exist.
