Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529836, here are decompositions:

17 + 31529819 = 31529836
53 + 31529783 = 31529836
167 + 31529669 = 31529836
269 + 31529567 = 31529836
389 + 31529447 = 31529836
557 + 31529279 = 31529836
563 + 31529273 = 31529836
587 + 31529249 = 31529836

Showing the first eight; more decompositions exist.
