Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31491496, here are decompositions:

233 + 31491263 = 31491496
263 + 31491233 = 31491496
293 + 31491203 = 31491496
347 + 31491149 = 31491496
353 + 31491143 = 31491496
419 + 31491077 = 31491496
557 + 31490939 = 31491496
677 + 31490819 = 31491496

Showing the first eight; more decompositions exist.
