Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462456, here are decompositions:

5 + 31462451 = 31462456
17 + 31462439 = 31462456
23 + 31462433 = 31462456
83 + 31462373 = 31462456
107 + 31462349 = 31462456
167 + 31462289 = 31462456
239 + 31462217 = 31462456
353 + 31462103 = 31462456

Showing the first eight; more decompositions exist.
