Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477560, here are decompositions:

7 + 31477553 = 31477560
11 + 31477549 = 31477560
17 + 31477543 = 31477560
47 + 31477513 = 31477560
53 + 31477507 = 31477560
113 + 31477447 = 31477560
131 + 31477429 = 31477560
137 + 31477423 = 31477560

Showing the first eight; more decompositions exist.
