Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446110, here are decompositions:

13 + 31446097 = 31446110
43 + 31446067 = 31446110
79 + 31446031 = 31446110
127 + 31445983 = 31446110
151 + 31445959 = 31446110
181 + 31445929 = 31446110
193 + 31445917 = 31446110
277 + 31445833 = 31446110

Showing the first eight; more decompositions exist.
