Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496270, here are decompositions:

7 + 31496263 = 31496270
61 + 31496209 = 31496270
97 + 31496173 = 31496270
109 + 31496161 = 31496270
151 + 31496119 = 31496270
229 + 31496041 = 31496270
349 + 31495921 = 31496270
373 + 31495897 = 31496270

Showing the first eight; more decompositions exist.
