Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462774, here are decompositions:

3 + 31462771 = 31462774
17 + 31462757 = 31462774
23 + 31462751 = 31462774
191 + 31462583 = 31462774
197 + 31462577 = 31462774
227 + 31462547 = 31462774
293 + 31462481 = 31462774
401 + 31462373 = 31462774

Showing the first eight; more decompositions exist.
