Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449256, here are decompositions:

23 + 31449233 = 31449256
173 + 31449083 = 31449256
227 + 31449029 = 31449256
239 + 31449017 = 31449256
269 + 31448987 = 31449256
347 + 31448909 = 31449256
353 + 31448903 = 31449256
359 + 31448897 = 31449256

Showing the first eight; more decompositions exist.
