Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462996, here are decompositions:

17 + 31462979 = 31462996
107 + 31462889 = 31462996
239 + 31462757 = 31462996
347 + 31462649 = 31462996
419 + 31462577 = 31462996
443 + 31462553 = 31462996
449 + 31462547 = 31462996
557 + 31462439 = 31462996

Showing the first eight; more decompositions exist.
