Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477774, here are decompositions:

23 + 31477751 = 31477774
191 + 31477583 = 31477774
197 + 31477577 = 31477774
347 + 31477427 = 31477774
593 + 31477181 = 31477774
827 + 31476947 = 31477774
857 + 31476917 = 31477774
953 + 31476821 = 31477774

Showing the first eight; more decompositions exist.
