Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462384, here are decompositions:

3 + 31462381 = 31462384
11 + 31462373 = 31462384
71 + 31462313 = 31462384
167 + 31462217 = 31462384
251 + 31462133 = 31462384
257 + 31462127 = 31462384
281 + 31462103 = 31462384
461 + 31461923 = 31462384

Showing the first eight; more decompositions exist.
