Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496244, here are decompositions:

23 + 31496221 = 31496244
71 + 31496173 = 31496244
83 + 31496161 = 31496244
103 + 31496141 = 31496244
233 + 31496011 = 31496244
347 + 31495897 = 31496244
397 + 31495847 = 31496244
443 + 31495801 = 31496244

Showing the first eight; more decompositions exist.
