Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496510, here are decompositions:

61 + 31496449 = 31496510
139 + 31496371 = 31496510
181 + 31496329 = 31496510
193 + 31496317 = 31496510
337 + 31496173 = 31496510
349 + 31496161 = 31496510
499 + 31496011 = 31496510
613 + 31495897 = 31496510

Showing the first eight; more decompositions exist.
