Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449584, here are decompositions:

3 + 31449581 = 31449584
7 + 31449577 = 31449584
13 + 31449571 = 31449584
31 + 31449553 = 31449584
163 + 31449421 = 31449584
181 + 31449403 = 31449584
211 + 31449373 = 31449584
223 + 31449361 = 31449584

Showing the first eight; more decompositions exist.
