Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461192, here are decompositions:

11 + 31461181 = 31461192
13 + 31461179 = 31461192
19 + 31461173 = 31461192
29 + 31461163 = 31461192
31 + 31461161 = 31461192
43 + 31461149 = 31461192
79 + 31461113 = 31461192
179 + 31461013 = 31461192

Showing the first eight; more decompositions exist.
