Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496836, here are decompositions:

17 + 31496819 = 31496836
53 + 31496783 = 31496836
167 + 31496669 = 31496836
263 + 31496573 = 31496836
269 + 31496567 = 31496836
317 + 31496519 = 31496836
347 + 31496489 = 31496836
419 + 31496417 = 31496836

Showing the first eight; more decompositions exist.
