Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496294, here are decompositions:

31 + 31496263 = 31496294
73 + 31496221 = 31496294
211 + 31496083 = 31496294
283 + 31496011 = 31496294
373 + 31495921 = 31496294
397 + 31495897 = 31496294
541 + 31495753 = 31496294
601 + 31495693 = 31496294

Showing the first eight; more decompositions exist.
