Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477852, here are decompositions:

11 + 31477841 = 31477852
41 + 31477811 = 31477852
53 + 31477799 = 31477852
59 + 31477793 = 31477852
71 + 31477781 = 31477852
101 + 31477751 = 31477852
269 + 31477583 = 31477852
281 + 31477571 = 31477852

Showing the first eight; more decompositions exist.
