Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477722, here are decompositions:

5 + 31477717 = 31477722
11 + 31477711 = 31477722
53 + 31477669 = 31477722
139 + 31477583 = 31477722
151 + 31477571 = 31477722
173 + 31477549 = 31477722
179 + 31477543 = 31477722
239 + 31477483 = 31477722

Showing the first eight; more decompositions exist.
