Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496514, here are decompositions:

73 + 31496441 = 31496514
97 + 31496417 = 31496514
193 + 31496321 = 31496514
197 + 31496317 = 31496514
251 + 31496263 = 31496514
293 + 31496221 = 31496514
353 + 31496161 = 31496514
373 + 31496141 = 31496514

Showing the first eight; more decompositions exist.
