Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462794, here are decompositions:

23 + 31462771 = 31462794
37 + 31462757 = 31462794
43 + 31462751 = 31462794
47 + 31462747 = 31462794
71 + 31462723 = 31462794
191 + 31462603 = 31462794
211 + 31462583 = 31462794
241 + 31462553 = 31462794

Showing the first eight; more decompositions exist.
