Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061872, here are decompositions:

3 + 1061869 = 1061872
5 + 1061867 = 1061872
23 + 1061849 = 1061872
41 + 1061831 = 1061872
89 + 1061783 = 1061872
101 + 1061771 = 1061872
113 + 1061759 = 1061872
173 + 1061699 = 1061872

Showing the first eight; more decompositions exist.
