Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496082, here are decompositions:

41 + 31496041 = 31496082
71 + 31496011 = 31496082
103 + 31495979 = 31496082
223 + 31495859 = 31496082
263 + 31495819 = 31496082
281 + 31495801 = 31496082
349 + 31495733 = 31496082
353 + 31495729 = 31496082

Showing the first eight; more decompositions exist.
