Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562794, here are decompositions:

17 + 31562777 = 31562794
83 + 31562711 = 31562794
167 + 31562627 = 31562794
173 + 31562621 = 31562794
191 + 31562603 = 31562794
227 + 31562567 = 31562794
251 + 31562543 = 31562794
293 + 31562501 = 31562794

Showing the first eight; more decompositions exist.
