Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576882, here are decompositions:

131 + 31576751 = 31576882
173 + 31576709 = 31576882
179 + 31576703 = 31576882
263 + 31576619 = 31576882
353 + 31576529 = 31576882
443 + 31576439 = 31576882
479 + 31576403 = 31576882
509 + 31576373 = 31576882

Showing the first eight; more decompositions exist.
