Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496028, here are decompositions:

17 + 31496011 = 31496028
79 + 31495949 = 31496028
107 + 31495921 = 31496028
131 + 31495897 = 31496028
149 + 31495879 = 31496028
181 + 31495847 = 31496028
227 + 31495801 = 31496028
271 + 31495757 = 31496028

Showing the first eight; more decompositions exist.
