Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461306, here are decompositions:

5 + 31461301 = 31461306
13 + 31461293 = 31461306
53 + 31461253 = 31461306
83 + 31461223 = 31461306
113 + 31461193 = 31461306
127 + 31461179 = 31461306
157 + 31461149 = 31461306
179 + 31461127 = 31461306

Showing the first eight; more decompositions exist.
