Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051180, here are decompositions:

3 + 1051177 = 1051180
23 + 1051157 = 1051180
29 + 1051151 = 1051180
41 + 1051139 = 1051180
101 + 1051079 = 1051180
173 + 1051007 = 1051180
281 + 1050899 = 1051180
293 + 1050887 = 1051180

Showing the first eight; more decompositions exist.
