Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466928, here are decompositions:

29 + 31466899 = 31466928
61 + 31466867 = 31466928
71 + 31466857 = 31466928
79 + 31466849 = 31466928
107 + 31466821 = 31466928
137 + 31466791 = 31466928
179 + 31466749 = 31466928
197 + 31466731 = 31466928

Showing the first eight; more decompositions exist.
