Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462276, here are decompositions:

3 + 31462273 = 31462276
59 + 31462217 = 31462276
149 + 31462127 = 31462276
173 + 31462103 = 31462276
269 + 31462007 = 31462276
353 + 31461923 = 31462276
383 + 31461893 = 31462276
389 + 31461887 = 31462276

Showing the first eight; more decompositions exist.
