Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477804, here are decompositions:

5 + 31477799 = 31477804
11 + 31477793 = 31477804
23 + 31477781 = 31477804
53 + 31477751 = 31477804
107 + 31477697 = 31477804
227 + 31477577 = 31477804
233 + 31477571 = 31477804
251 + 31477553 = 31477804

Showing the first eight; more decompositions exist.
