Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529788, here are decompositions:

5 + 31529783 = 31529788
71 + 31529717 = 31529788
107 + 31529681 = 31529788
137 + 31529651 = 31529788
281 + 31529507 = 31529788
317 + 31529471 = 31529788
467 + 31529321 = 31529788
509 + 31529279 = 31529788

Showing the first eight; more decompositions exist.
