Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477608, here are decompositions:

5 + 31477603 = 31477608
31 + 31477577 = 31477608
37 + 31477571 = 31477608
47 + 31477561 = 31477608
59 + 31477549 = 31477608
101 + 31477507 = 31477608
179 + 31477429 = 31477608
181 + 31477427 = 31477608

Showing the first eight; more decompositions exist.
