Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113978, here are decompositions:

31 + 113947 = 113978
79 + 113899 = 113978
181 + 113797 = 113978
199 + 113779 = 113978
229 + 113749 = 113978
331 + 113647 = 113978
421 + 113557 = 113978
439 + 113539 = 113978

Showing the first eight; more decompositions exist.
