Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045920, here are decompositions:

13 + 1045907 = 1045920
17 + 1045903 = 1045920
61 + 1045859 = 1045920
79 + 1045841 = 1045920
101 + 1045819 = 1045920
157 + 1045763 = 1045920
181 + 1045739 = 1045920
191 + 1045729 = 1045920

Showing the first eight; more decompositions exist.
