Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 946872, here are decompositions:

11 + 946861 = 946872
13 + 946859 = 946872
19 + 946853 = 946872
53 + 946819 = 946872
71 + 946801 = 946872
89 + 946783 = 946872
103 + 946769 = 946872
131 + 946741 = 946872

Showing the first eight; more decompositions exist.
