Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461170, here are decompositions:

7 + 31461163 = 31461170
43 + 31461127 = 31461170
157 + 31461013 = 31461170
163 + 31461007 = 31461170
193 + 31460977 = 31461170
199 + 31460971 = 31461170
241 + 31460929 = 31461170
331 + 31460839 = 31461170

Showing the first eight; more decompositions exist.
