Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042072, here are decompositions:

29 + 1042043 = 1042072
71 + 1042001 = 1042072
89 + 1041983 = 1042072
179 + 1041893 = 1042072
293 + 1041779 = 1042072
401 + 1041671 = 1042072
419 + 1041653 = 1042072
509 + 1041563 = 1042072

Showing the first eight; more decompositions exist.
