Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462302, here are decompositions:

13 + 31462289 = 31462302
29 + 31462273 = 31462302
199 + 31462103 = 31462302
233 + 31462069 = 31462302
281 + 31462021 = 31462302
353 + 31461949 = 31462302
359 + 31461943 = 31462302
379 + 31461923 = 31462302

Showing the first eight; more decompositions exist.
