Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477554, here are decompositions:

5 + 31477549 = 31477554
11 + 31477543 = 31477554
41 + 31477513 = 31477554
47 + 31477507 = 31477554
71 + 31477483 = 31477554
107 + 31477447 = 31477554
127 + 31477427 = 31477554
131 + 31477423 = 31477554

Showing the first eight; more decompositions exist.
