Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520662, here are decompositions:

3 + 31520659 = 31520662
83 + 31520579 = 31520662
179 + 31520483 = 31520662
263 + 31520399 = 31520662
269 + 31520393 = 31520662
353 + 31520309 = 31520662
419 + 31520243 = 31520662
461 + 31520201 = 31520662

Showing the first eight; more decompositions exist.
