Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461164, here are decompositions:

3 + 31461161 = 31461164
37 + 31461127 = 31461164
127 + 31461037 = 31461164
151 + 31461013 = 31461164
157 + 31461007 = 31461164
193 + 31460971 = 31461164
313 + 31460851 = 31461164
331 + 31460833 = 31461164

Showing the first eight; more decompositions exist.
