Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113990, here are decompositions:

7 + 113983 = 113990
43 + 113947 = 113990
181 + 113809 = 113990
193 + 113797 = 113990
211 + 113779 = 113990
229 + 113761 = 113990
241 + 113749 = 113990
271 + 113719 = 113990

Showing the first eight; more decompositions exist.
