Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462776, here are decompositions:

5 + 31462771 = 31462776
17 + 31462759 = 31462776
19 + 31462757 = 31462776
29 + 31462747 = 31462776
47 + 31462729 = 31462776
53 + 31462723 = 31462776
127 + 31462649 = 31462776
167 + 31462609 = 31462776

Showing the first eight; more decompositions exist.
