Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 50000, here are decompositions:

7 + 49993 = 50000
43 + 49957 = 50000
61 + 49939 = 50000
73 + 49927 = 50000
79 + 49921 = 50000
109 + 49891 = 50000
157 + 49843 = 50000
193 + 49807 = 50000

Showing the first eight; more decompositions exist.
