Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477556, here are decompositions:

3 + 31477553 = 31477556
7 + 31477549 = 31477556
13 + 31477543 = 31477556
43 + 31477513 = 31477556
73 + 31477483 = 31477556
109 + 31477447 = 31477556
127 + 31477429 = 31477556
157 + 31477399 = 31477556

Showing the first eight; more decompositions exist.
