Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530064, here are decompositions:

3 + 31530061 = 31530064
47 + 31530017 = 31530064
131 + 31529933 = 31530064
173 + 31529891 = 31530064
281 + 31529783 = 31530064
347 + 31529717 = 31530064
383 + 31529681 = 31530064
557 + 31529507 = 31530064

Showing the first eight; more decompositions exist.
