Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45900, here are decompositions:

7 + 45893 = 45900
13 + 45887 = 45900
31 + 45869 = 45900
37 + 45863 = 45900
47 + 45853 = 45900
59 + 45841 = 45900
67 + 45833 = 45900
73 + 45827 = 45900

Showing the first eight; more decompositions exist.
