Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462342, here are decompositions:

3 + 31462339 = 31462342
29 + 31462313 = 31462342
53 + 31462289 = 31462342
239 + 31462103 = 31462342
419 + 31461923 = 31462342
449 + 31461893 = 31462342
491 + 31461851 = 31462342
563 + 31461779 = 31462342

Showing the first eight; more decompositions exist.
