Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461196, here are decompositions:

3 + 31461193 = 31461196
5 + 31461191 = 31461196
17 + 31461179 = 31461196
23 + 31461173 = 31461196
47 + 31461149 = 31461196
83 + 31461113 = 31461196
149 + 31461047 = 31461196
269 + 31460927 = 31461196

Showing the first eight; more decompositions exist.
