Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576776, here are decompositions:

17 + 31576759 = 31576776
37 + 31576739 = 31576776
67 + 31576709 = 31576776
73 + 31576703 = 31576776
103 + 31576673 = 31576776
137 + 31576639 = 31576776
157 + 31576619 = 31576776
193 + 31576583 = 31576776

Showing the first eight; more decompositions exist.
