Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461374, here are decompositions:

13 + 31461361 = 31461374
31 + 31461343 = 31461374
73 + 31461301 = 31461374
151 + 31461223 = 31461374
181 + 31461193 = 31461374
193 + 31461181 = 31461374
211 + 31461163 = 31461374
337 + 31461037 = 31461374

Showing the first eight; more decompositions exist.
