Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462294, here are decompositions:

5 + 31462289 = 31462294
167 + 31462127 = 31462294
191 + 31462103 = 31462294
317 + 31461977 = 31462294
401 + 31461893 = 31462294
443 + 31461851 = 31462294
503 + 31461791 = 31462294
557 + 31461737 = 31462294

Showing the first eight; more decompositions exist.
