Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461174, here are decompositions:

11 + 31461163 = 31461174
13 + 31461161 = 31461174
47 + 31461127 = 31461174
61 + 31461113 = 31461174
127 + 31461047 = 31461174
137 + 31461037 = 31461174
163 + 31461011 = 31461174
167 + 31461007 = 31461174

Showing the first eight; more decompositions exist.
