Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496276, here are decompositions:

13 + 31496263 = 31496276
67 + 31496209 = 31496276
103 + 31496173 = 31496276
157 + 31496119 = 31496276
193 + 31496083 = 31496276
379 + 31495897 = 31496276
397 + 31495879 = 31496276
457 + 31495819 = 31496276

Showing the first eight; more decompositions exist.
