Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462350, here are decompositions:

11 + 31462339 = 31462350
37 + 31462313 = 31462350
61 + 31462289 = 31462350
83 + 31462267 = 31462350
223 + 31462127 = 31462350
281 + 31462069 = 31462350
347 + 31462003 = 31462350
373 + 31461977 = 31462350

Showing the first eight; more decompositions exist.
