Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47990, here are decompositions:

13 + 47977 = 47990
43 + 47947 = 47990
73 + 47917 = 47990
79 + 47911 = 47990
109 + 47881 = 47990
181 + 47809 = 47990
193 + 47797 = 47990
199 + 47791 = 47990

Showing the first eight; more decompositions exist.
