Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045912, here are decompositions:

5 + 1045907 = 1045912
53 + 1045859 = 1045912
71 + 1045841 = 1045912
83 + 1045829 = 1045912
113 + 1045799 = 1045912
149 + 1045763 = 1045912
173 + 1045739 = 1045912
233 + 1045679 = 1045912

Showing the first eight; more decompositions exist.
