Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461308, here are decompositions:

7 + 31461301 = 31461308
79 + 31461229 = 31461308
127 + 31461181 = 31461308
181 + 31461127 = 31461308
271 + 31461037 = 31461308
331 + 31460977 = 31461308
337 + 31460971 = 31461308
379 + 31460929 = 31461308

Showing the first eight; more decompositions exist.
