Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547836, here are decompositions:

3 + 31547833 = 31547836
53 + 31547783 = 31547836
227 + 31547609 = 31547836
317 + 31547519 = 31547836
347 + 31547489 = 31547836
479 + 31547357 = 31547836
569 + 31547267 = 31547836
659 + 31547177 = 31547836

Showing the first eight; more decompositions exist.
