Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462338, here are decompositions:

71 + 31462267 = 31462338
197 + 31462141 = 31462338
211 + 31462127 = 31462338
269 + 31462069 = 31462338
317 + 31462021 = 31462338
331 + 31462007 = 31462338
359 + 31461979 = 31462338
389 + 31461949 = 31462338

Showing the first eight; more decompositions exist.
