Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462836, here are decompositions:

5 + 31462831 = 31462836
29 + 31462807 = 31462836
43 + 31462793 = 31462836
79 + 31462757 = 31462836
89 + 31462747 = 31462836
107 + 31462729 = 31462836
113 + 31462723 = 31462836
227 + 31462609 = 31462836

Showing the first eight; more decompositions exist.
