Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462270, here are decompositions:

3 + 31462267 = 31462270
53 + 31462217 = 31462270
137 + 31462133 = 31462270
167 + 31462103 = 31462270
263 + 31462007 = 31462270
293 + 31461977 = 31462270
347 + 31461923 = 31462270
383 + 31461887 = 31462270

Showing the first eight; more decompositions exist.
