Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042912, here are decompositions:

11 + 1042901 = 1042912
83 + 1042829 = 1042912
113 + 1042799 = 1042912
131 + 1042781 = 1042912
179 + 1042733 = 1042912
281 + 1042631 = 1042912
293 + 1042619 = 1042912
383 + 1042529 = 1042912

Showing the first eight; more decompositions exist.
