Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461144, here are decompositions:

17 + 31461127 = 31461144
31 + 31461113 = 31461144
97 + 31461047 = 31461144
107 + 31461037 = 31461144
131 + 31461013 = 31461144
137 + 31461007 = 31461144
167 + 31460977 = 31461144
173 + 31460971 = 31461144

Showing the first eight; more decompositions exist.
