Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462336, here are decompositions:

23 + 31462313 = 31462336
47 + 31462289 = 31462336
233 + 31462103 = 31462336
359 + 31461977 = 31462336
443 + 31461893 = 31462336
449 + 31461887 = 31462336
557 + 31461779 = 31462336
593 + 31461743 = 31462336

Showing the first eight; more decompositions exist.
